Bring the idle up a bit. Makes life easier. Half a dozen cammed foxes over 20 years never had the stalling problem. The bucking at low RPM, sure.
Yeah, but then the idle won't sound as sweet.
@@EASTCOASTIMPERIALTry to find a middle ground. Find the lowest possible idle rpm’s that it won’t stall and go for it
I've found the lowest possible rpm doesn't always sound the best. On my Chevy 950rpm is bliss it's right in between chop patterns so it swaps occasionally.
Great video and real picture of cam life with a fox body! Good job showing the way cams can rear their issues. Probably the only video addressing this and informative for those thinking about going this route.
Thanks so much my friend! Much appreciated
I have the attention span of a small shrub. That being said, I watch all of your videos in their entirety.
So well done, great delivery of facts and opinions. Thank you for taking the time to puit these vids together for all of us Fox fans brother🙂
Hahahaha I love the analogy 😂😂. Thanks so much buddy. I really appreciate your kind words and taking the time to reach out 🙏🙏🙏🦊🦊🦊
Just got a fox and its cammed. You explained everything so now I understand what was going on around 1500 RPMs. Thanks man.
Right on - you're welcome!
These intermittent bugs are the hardest to diagnose since they don't do it all the time. Nice to see someone showing the real world expectations of a modified foxbody! Great video bud!
Thanks so much for the kind words buddy! And yes - you are so right. Try telling a mechanic: "Well, it only does it sometimes..." 😂
Dude the car is made for EXERCISING GOING THROUGH THE GEARS
Nice video Mate. Always good to hear some balanced views. There are pros and cons to everything we do to these cars and it helps to get that info before making a decision. Thank you.
And yes…please do a video on the old mags! 👍👍👍
Thx buddy!!! Ok will do
Beauty car man! Looks like you’re a local BC guy in Kelowna. My 87’ 5.0 LX Hatchback had a B303 cam with the exact same kwirks. Could never figure it out, but that car never gave me any real issues in the 4 years I had it. I absolutely regret selling it, and I’m now looking for another foxbody notchback. You got a new subscriber! Cheers
Thank you sir! Yes, you have a good eye 😉
Man you have to be good with the clutch and the gas eh buddy?! Gotta be able to multitask for sure. Great vid!
Hahaha it’s so true! Thx pal 👊
Just found your channel. Great job on this video. I am also having same issues with the cam. I have thought maby it was a mass air or timing issue. My car runs great but like you said, can be frustrating. Anyhow thanks again and really appreciated this video! Love the emerald green lx coupe! I have a 93 lx silver coupe.
Hey buddy! Thanks for the kind words! Yes, it can be frustrating at times. I do have another video where I’ve made some improvements to the bucking that you may find interesting 👍
Love the channel. I drove a f cammed mustang years ago for 4 years in mn winter. It was awsome😀
Thx buddy! Hahaha that’s awesome!
After I added all the standard bolt on’s, GT-40 heads, cam, throttle body, etc I ran into the same sporadic idle issue. My problem ended up being the TPS being in the wrong position voltage wise. Mine did EXACTLY what his does in this video too. As soon as I set it correctly with a multi meter, the idle sits perfect, cold or at running temp. No dips or subtle crashes. Look up videos on setting the TPS voltage and you may fix your issue too. It’s also SUPER easy to do.
Mine did also I figured it out it was the junk gas at the pump! As soon as I put race gas in it ran absolutely perfect. The reason being Is the race gas was 100 octane. The pump gas was 93 but was it? The problem was pump gas burns eradic and race gas burns cosistant.
Hell yeah just got off work. Gonna get me a beer and watch this. Looking for a cam soon too
Nice thanks buddy!
Great clip Gary. I know of those issues that stem down to all makes and models and it's the most manageable with a manual car. When you put those cams in an AOD car it's even worse. That's the only reason why I haven't cammed my car really is just for driveability. Other than that it sounds great and am sure runs strong.
Thanks Rob! Yes very good points you bring up. I couldn't imagine driving an auto and having it fall on its face in traffic 😬
Bumping up the idle to 900-1000 def helps with it's want to stall, running a tf stage 2 in my 93, cold starts always seem perfect, hot starts have minimal idle hunt, but the in between cold and hot has a fair bit of idle hunting but only lasts 5-10 secs before it gets happy. Wanting to get a quarter horse for it and see what leech can do to tune it personally. Another good video bud, and your right, not a lot of people address this.
Thanks a lot buddy! Appreciate you weighing in on the subject 👊
I run mine at 900rpm. I tried to drop it to hear the lope better but too much surging below 900rpm.
My favorite foxbody channel. Literally relate to everything Lmaoo for the longest i thought my car was just horrible. Now i know all foxbodys have the SAME problems lol it’s apart of owning one
Awe thx pal!! Hahaha it’s so true! Maybe I should change my channel name to “The Foxbody Psychologist” 😂👊
Fox body guy here would like to thank you for your time and information
You’re welcome sir!!! Thank you very much
Nice video and interesting topic!
2:11 Yeah that would be cool!
A Throwback kind of video.
Thanks so much pal! Ok sounds good 👍
@@KASLCustoms You're welcome! 👍
Love your soft top I had the same model wished I never sold it! So much fun!
Than you!
Thanks for the informative video 🇨🇦 🇺🇸
No problem!! 🙏🙏🙏
U must be in the Okanagan because that intro to this video looked a lot like the okanagan! Makes me miss home! Great video man! I love Foxes
Yup. Thanks buddy!
Same thing with mine. Messed and messed with it. Finally turned the idle up and no more surging. Kind of sucks having a 900 rpm but its runs so much better.
👍
Awesome video! Please do a video with the old mustang magazines.👍🐺
Thx pal. Ok sounds good 👍
Awesome video brother!!! Yea those Mags would be awesome to see!!! A Fox can definitely make you develop a Love/hate relationship with it if you don’t learn how to drive it. Lol
Thanks so much buddy! hahahaha - so true! Ok I will get working on a Mag video for everyone 👍
All good things! Hehe. FOX mustangs are Driver’s cars to be sure. My first FOX was in 1994, I have had a 93 GT since 2000, overall my fourth FOX mustang. It’s powered by a CHP 331 with a trick flow stage 2 542/563 split pattern cam. Fun car and yes it does the typical things you’ve showcased. Although I haven’t had any issues on restart after a gas & go and hope it stays that way.
Again these cars are meant for drivers once they’ve been modded to this extent. That’s the simplicity and one of the many reasons I enjoy them.
Nice video and I’m a new subscriber now. Thanks
That’s awesome buddy. Thanks so much for the kind words and also thank you for sharing your story. I always love when people do because I think it helps our fox community grow and help one another out. Thanks again buddy and enjoy that car!!!
Ya I think that would be a fun video pulling out the mags and looking at some of the old articles. My father in law gave me a mag from 1986 where they compared the 86 GT to the grand national. It really brought me back
thats awesome! Ok sounds good buddy!
That’s awesome
I had a similar problem, I can almost guarantee it's the positive vent from the tank constantly/ intermittently letting fumes into your intake. Especially after a fill up. A quick test , just un plug that vapor line from tank and seeif it fixes it. Good luck
Interesting - I will look into that. Thank you
Yes please do a video of those magazines. I have a ton of them.
Sounds good buddy!
Awesome video. Thanks for sharing. I thought it was was my IAC
No problem!
Just have completed my nostalgia H.C.I. a few weeks ago with gt40 heads and intake. I chose the E-303 cam because my 91LX is an AOD car. Yes, you totally have to relearn how to drive your car. After about 20 base idle resets to try to find the sweet spot for the idle, I found my car is happy idling around 650-700 RPMs. Anything less than that and it will die when stopping at a traffic light. Conversely I can't go higher than about 900 RPM on the idle or I will loose to much vacuum and the power brake booster will not function. I like having brakes. The E-303 is interesting with the AOD, about the time the torque converter is locking, the cam starts coming alive. So you get a good solid spin free launch before the cam kicks in, but when it kicks in you definitely feel it.
Right on! That is great information - thanks so much for sharing!
I feel the E cam is very well balanced for a car that will be driven, for lack of a better term, normally. It does work nicely with the automatic transmission, although my car has the transmission worked on, with a higher stall speed non-locking torque converter.
Coming from someone with a cammed 5.0 but in an Explorer platform knew just from the title what this would be about and was right lol. I too deal with intermittent stalls if I don't two pedal. For me it occurs going from P into D / R, or vice versa especially with the wheel turned. I just live with it as a tradeoff for having a choppy cam. Drives good otherwise but do wish my torque curve was a tad lower. Great video!
Hahahaha so true!
Thx for reaching out 👍
Always a sweet looking Foxx, yesssirrrr
Thx bud!
Funny I have the same issues! I have an e-Cam nice lumpy idle not to aggressive, but do have some issues like you are saying like an old two stroke. I found that if I keep it in gear as I roll up to a light or stop sign almost till I come to a dead stop it doesn’t stall. And I do need to nurse it from a start kind of rev it as I let the clutch out. Most of the time can’t just let clutch out without feathering the gas or it falls on its face. I’ve noticed here in Michigan as it’s gotten less humid it seems to run much better. I’ve been thinking of the ProM system because of it. Glad you addressed this cause It makes me feel like I constantly need to tinker with it to make it perfect. And there probably is no such thing!lol
Hey Bob! LOL yeah it is so true my friend. That is interesting the ways you have found to work around the surging when coming to a stop. Mine is the opposite where I need to pull it out of gear at speed, coast in neutral and use the brakes. This seems to keep mine from bogging down 🤷♂️😂. Honestly, I think the car is as close to perfect as one could get it however us stubborn old buggers want to try and make it run like a brand new car. I guess thats what makes the hobby fun 😉
I have the XE 274 HR camshaft with GT 40 heads. Mine does that same surging at start up goes away after a minute or so. I’m told that it goes into close loop after a minute or so. I set the idle a little bit higher to help. Glad to know I’m not the only one. I thought I had a vacuum leak or something.
Love
viedos sir
That’s why the Ford Motorsport E303 or F303 cams were the best cams in my opinion for what I had and looks like would be perfect for what you are wanting…
Love the videos! No seat belt is risky man
Thanks buddy!
There's an old saying "you can't have your cake and eat it too" if you want to change out the stock mild cam for something that will provide increased performance something has to give and that typically is drivability. I owned a 90 notchback that had several cams throughout the 13 years with the first one being a B303, it had drivability issues but I tuned most out with an EEC Tuner and just lived with the remainder by learning to drive in a manner that made issues less annoying.
Well said
My 89 has the B303 and had the surging idle, done the base idle reset and now idles at 850-900 at temp with no surging.
Great videos as always brother and love your new intro video! Car looks and sounds amazing!! Reason I haven’t really messed to much with my motor is that it is still Speed Density. I haven’t converted over to Mass Air. Have heard that these Speed Density cars do not like changes made. Wonder if that is true??
Thanks so much buddy! Yeah the speed density cars don't react as nicely as the mass air cars to cam shaft changes.
Speed density cars HEAVILY rely on the vacuum signal to the EEC processor. With no mass air meter to actually measure the amount of air coming in…the SD cars use a table with predetermined value’s based off of the stock components flow capabilities/vacuum capacity. If the aftermarket cam you choose drastically reduces vacuum (especially at idle) you’re gonna run into issues. Look for a performance cam with a similar to OE lobe separation angle. That will keep the vacuum related gremlins in check.
Well said 👍
That news video clip you used was next to my house where I live in Austin TX.... LOL
Oh really!? 🤣👊
Not just limited to 5.0. I have a 4.6 2v I dropped cams in a year ago, and run into the same. Granted it's not often, but have have had a few stalled start ups, and remember one in reverse (picking daughter up from school). Also noticed it struggled at idle when I had the heater on back in spring one morning. All in all not terrible, but definitely changes the characteristics. Also did have mine professionally tuned right after I finished, so it's just a thing.
Yessir well said
I was taught the same way... as far as down shifting and using the engine to slow the car down and save the brakes. I got near 100000 miles before having to change brakes on my Mazda 3 hatch commuter car. It has close to 200000 miles on the factory clutch. I sure do miss the Stang....
Yessir! Thats great brake and clutch life!!!
Great video and demo of the issues! A shop told me the “idle hunt” issue can’t be tuned all the way out. Perhaps it can be tuned out if a person changes from the stock A9L to an aftermarket computer and then has a good tune it will stop the idle hunt. For me the sound of the lumpy idle and other benefits is well worth the other minor issues. 💯👊🏾
Leech can fix it
hahaha amen brother! The fella that tuned my car is VERY knowledgable and he has "re tuned" it to try and fix my sporadic issues. All that said, I'm of the opinion that I am about as good as an old foxbody is going to get 😉
@@KASLCustoms I hear ya Brother! As long as you can still drive the Fox, enjoy it and look good doing it… it’s worth dealing with the little nuances that come from an older car. 💯👊🏾🍻
@@hotrodray6802 Leech is awesome Bro. I am sure they could do it! 💯👊🏾
Yes. It's all in the computer. The computer is controlling fuel and spark and idle air, by taking electronic signals from multiple reference points, and it's trying to determine the right course of electronic signal to send to components to make physical changes to control the "anomaly" that it is detecting. This is why I prefer good old fashioned carbs and vacuum advance on my Fox cars. I've honestly been able to get them to run perfect with hipo parts.
Depends on your cams duration . My 86 capri is still speed density. I have a old school crane 2030 cam . 533/544 lift cam . With 224 duration . Had same issue . Got 98% of the issues tuned out of it . Bumped idle to between 750 and 850 . And fixed all vacume leaks . Sometimes it will still surge at idle but no longer dies at a red light . It's a real pain in the a$$ but can be done .
Yessir - I hear ya!
Try the Lunati Voodoo 20350710. I'm running that in my stock block GT40 top end and it is amazing. The voodoo line was developed by Harold Brookshire one of the top cam designers in North America. If you start reading around (forms) the voodoo lineup out preforms the equivalent comp cams extreme energy cam with area under the curve which is more important than a single peak number.
Thanks for the advice my friend! I will definitely have a look for my GT40 build. Thank you!
Stroke it to a 347 which will make that cam seem a little smaller, but with the added stroke and that cam you would have a nicer set-up
LOL - sounds easy enough 😂👊
I had a 92 LX, Same Color, Deep Emerald Green. Currently considering painting my S550 the same color.
Nice!
I have the same cam in mine. Yes, it did the same, thing especially when it's still cold. I noticed when I unplugged one of the connections on the vacuum tree it stopped. I have the holley terminator x in mine. Its speed density anyways so it's like cracking open the throttle body a bit more. It purrs now. Great video bro! I liked the b303 a bit more. It might throw that back in.
Thanks so much bud 👊. Interesting that even with the Holley you’re dealing with this 🤔
@89fox
Why do you prefer the b cam instead?
I’m sold on custom grind camshafts. The off-the-shelf cams are decent, but nothing beats one cut for your combination, needs and driving style. I’m running a 347 with AFR 185 heads, Holley Systemax intake, 1.6 rockers and Holley Terminator-X. I have posted on your channel the details before but it’s hard to beat one built just for you. Mine is a billet camshaft and for just under $400, it does what I need and want. Plenty of vacuum for the brakes, great idle and snappy response. It’s .600/.595, 227/231 with 112 lobe separation, over 370 lb/ft and 400hp to the wheels, I’m still trying to maximize it.
Very nice! Sounds like a nice cam
Intro is 🔥 🔥 🔥
Thanks pal!
Yes it can be tuned to remove the idle hunting but it requires a faily good aftermarket ECU with a good tuner...
This is why, even with efi, I went with a stock speed density cam and quality 1.7 rollers on my TW heads. I don't need max power and like the long runner grunt.
👍👍👍
An EFI upgrade, even when i had a Classic FAST system made my cammed fox idle like butter. But it still bucked at low RPMs 😅
Overall good video but you touched on the issue. It’s your ecu. I have a much more radical build and have more issues with the twin disc than I do the cam hunting and surging. Not everyone can afford or wants to but a Holley EFI stand alone will give much more accurate timing control and no more issues.
Have you considered the additional load on the engine when off the throttle, turning the steering wheel, and on the brakes?
My 91 has edelbrock heads, intake, etc with a trick flow stg1 and I love it.
The larger brake booster helps this also.
The IAC restriction plate also helped.
I've been messing with this thing for 12yrs...lol
Hahaha I hear you bud
1989 DECH LX full skirts and trunk not hatch. I miss that car as it had my .351 Cleveland in it. For shits and giggles? It pulled the 750 Kawi Jetski. Yup! I perf'd her too. Stainless Steel Impeller and bored and ported with the straight out pipe.
Idle air control mod ford makes a kit for the throttle body! I had 306 E cam Afr165s on a DSS 306 stroker cured my idle issue
Off topic, but what is the biggest cam i can put in my 5.0 that has trick flow 170 heads and 1.7 rockers?
These issues can be tuned out with a proper tune or ecu upgrade. I’ve done mine and recommend Leech motorsports, they have an account on here. They are very good at stock ecu tunes and terminator x.
Thx buddy 👍
Even on a carbed cammed car I always set idle to 800-900. Never had issues with air running at idle etc.
Excellent 👌
Same thing was happening on my newly cammed LS3 camaro. Tuned it out though. Never happened again
Is the smoke machine a factory option? Maybe it stows with the jack and spare.
When I did my gt40 swap I was going nuts trying to figure what cam I wanted to the point I left my stock one in but I did put a set of cobra roller rockers I’m happy but I do like that lumpy idle .
Yeah thats not a bad choice at all bud! The lumpy idle is cool but the stock cam characteristics are also VERY hard to beat...
E cam is great for every day with some lump. I love mine and it’s a great cruiser.
Hi , Thank you for all your videos and your channel. I have watched this video a few times very informative, however my car like yours has a HCI with Trick Flow 170 11R's, Trick flow track heat intake, an Erson camshaft slightly larger than than Trick flow stage 1 cam, but very similar though, also a Pro M 75mm Mass Air with Pro M 30 LBS fuel injectors and a BBK 155 LPH fuel pump and BBK 1 5/8 Shorty unequal headers, 373 gears... just to give an idea of my mods. My car had all the very same problems mentioned in your video here. Plus it would stall randomly while cruising, or at speed, VERY dangerous to say the least!! So I went to Leech Motorsports, and had Matthew Harrison remote tune my car, as I am in Ontario, Canada. He IS an absolute tuning genius let me tell you. I installed a Moates Quarterhorse Datalogger/chip, yes it does both and holds up to 8 tunes that can be switched on the fly, you cannot do this with an SCT chip. I ditched my SCT chip. I would then data-log in my 1989 Fox Body coupe 5 speed, with a laptop. I'm on tune number 8, and with each and every data-log and tune update, the car has gotten better and better. And let me say when Matt built the 1st tune, all my cars drivability issues stopped, completely. It idles and drives so smooth let me tell you. Sounds like your tuner created a good tune for you, but I think it could be improved.... I talked with Tec Motion. Great guy he is. But there is a tuning parameter in the Ford Software called Dashpot. It is responsible for idle air control, and throttle tip in and tip out, and decel, this is where a vehicle spends most of it's time, where tuning a proper fuel map and timing with accurate dashpot tuning works out these bugs. This is what your car or anyone's modified Fox Body Mustang needs, this will be the icing on your cake, trust me. I have learned a lot from Matt about tuning parameters. Dashpot tuning through datalogging and tuning can and will fix these problems. And a good tuner should know this. My car no longer suffers from the problems mentioned in this video...at all!!!! Also most tuners turn off the factory O2 sensors, mine are functional in the tune, and adjust and fine tune the cars fuel needs.
We are going to continue in the spring after the winter is over, we are finalizing the tune for WOT. We have been doing this with a Innovate Wide-band O2 sensor. Dashpot tuning can be achieved better through data logging and real world driving of your vehicle, not so much on a Dyno unless multiple dyno pulls are made, and not all at full throttle. Some must be made at part throttle and cruise simulation on the street. A data log is used to work out the final finesse of part throttle cruising and in town driving, so with data-logging, and with real world street driving this can be achieved. No one should have to settle for less. So far my car makes 323 horse and 323 LBS torque to the wheels and gets decent mileage, with spirited driving and cruising I can achieve 390 to 425 KM's per tank with zero issues and all with with in town drivability. My Erson Cam.320 lift at .050, .512 lift intake and exhaust with 1.6 roller rocker, 60 degrees overlap, and an 112 LSA. It pulls 16 inches of vacuum at idle. It has and Rpm band of 2500 to 6500. Your cams vacuum should have about the same, about 15 to 17 inches of vacuum, which is more than enough for operating brakes, with decent idle, and while giving great drivability around town and on the street at low RPM and part throttle cruise. Hope this helps you, or any Fox Body Mustang 5.0 owner who is ready to rip out their hair!!!! Remember it's all in the tune!!
Hello Bill. Wow - thank you so very much for taking the time to write all of that down for me. Much appreciated!!! I will most definitely take this information and see what I can do with it. As for the video you mention, I did not get one. If you don't mind, can you send it over again? Alternatively, my email is listed on the "about" tab of my TH-cam channel under "business enquiries" Thanks again!
@@KASLCustoms Hi Gary I sent you the video and info to your business email, hope it helps.....:-)
I got it thanks buddy!
My cam fox body does the same thing more noticeable for me when it’s cold
@KASL Customs i just recently found your channel. A lot of good info. My dad bought a 90 convertible lx brand new, one of the manual 7/up cars. It was just handed down to me. Loved that car when i was a teenager. It’s extremely low miles, all the factory paperwork/window stickers/ pictures of the car on the dealership floor, original car cover, convertible cover, factor ford leather bra etc etc etc…., in perfect condition and bone stock. been wondering what to do with it tbh. i was told because of what it is and its condition to leave it stock. It’s been under cover its whole life and i cant take it anywhere without someone trying to buy it. i want to do a few things to it but still debating if i should. After seeing the one they auctioned off that was an auto with more miles and with mine being in better condition that it…. Makes me pause and wonder if i should leave it alone. but i really want to cam it, regear the rear end, do a 5 bolt conversion with wheels, and lower it two inches and just have fun with it like i did 25 years ago. if you know what i should do please let me know because i cant make up my mind lol. just took it out of its sleeping spot for its annual fluid changes and detail just to cover it back up for another year… thats been its life for 20 years. Seems wrong to not drive it and have fun…
Send me a message on my website - KASLCustoms.com I think I can help
ilde plate on the front of the IAC has two allen head bolts to help adjust the added air and lack of vacuum.
Thanks for sharing - However I'm not sure what you're referring to regarding the "Idle Plate?"

@@Jontfs300 Thank you!
Ha! It’s nice to see you suffer the same problems I have 😅😂. Seriously though it does get frustrating as hell. Mine is fine on cold start but will surge / hunt hard sometimes on a hot start. Even like at a show when it has sat a few hours but had some heat in it, not a full cold start, it will surge. As well as the stalling you mentioned on deceleration.
Yeah bud! I’m looking forward to riding in that stunner. Knowing that you’re show stopper runs just as terrible as my bucket always makes me feel better 😉😂👊
@@KASLCustoms let’s hope I get this transmission fixed before then or we will be pushing this show stopped into the show 😂
Hahahahaha!!!
I went with a trickflow stage 1 I like it
Vacuum behaves differently in different environments. Warmer air is better for it. So, take that into consideration with a cammed fox body. I enjoyed this part of owning a vehicle almost exactly like this back in the day. You got to learn how it wants to be treated. Same with running different drilling rigs. Each vehicle had a mind of it's own and figuring out how to "fix" these quirks ruins the fun.
Well said
Mine is weird it hunts for the idle and then it will stall when I first start it then I restart it and it’s good
Yeh, bump up your idle and check your IAC. Swap it out with your other car and see if it still does it. They are famous for not opening all the way
Thanks buddy!
If it was me I'd check the timing then do a base idle reset if that didnt fix the issue I'd do a tune up and install a aftermarket ignition system and 3g alternator. My thought is upgrade the spark and beef up the electric system so there is no low voltage issues.
Vacuum you say? Hmm that is interesting, I myself would have probably guessed that your valve springs were not the right ones to be running with that cam. I also would look at the TPS module with a multimeter and dial that thing in to the proper spec for your cam. BTW did you reset your idle after you changed the cam? If not be sure you do that before you mess with the TPS. Finally if you feel certain about it being caused by low vacuum you can always put a vacuum booster on it from Hoover, LOL. Anyway I hope this helps you solve your problems. BTW damn good looking cars you have man, good luck
Thanks for reaching out. The valve springs are the ones that came on the AFR 165 heads, the needs were brand new when installed and everything checked out on them. TPS was checked and set and so was the base idle reset. I have also considered trying a vacuum pump 👍
My 93 notch does the same things at stop light and fall on its face in slow reverse also rpm stuck high a bit at times when I’m in rev happy mode sometime yes I’m thinking tuning to smooth thing out…
Yeah if it’s not tuned i would say to start there first and see if it clears up 👍
Did you have to check piston to valve clearance for this cam or is it one to not worry about? I have trickflow 170 heads with 1.6 rockers
Hey bud - I did check (just to be safe) however I was all clear 👍
Ok my fox definitely does this a lot. I have adjusted my idle up to 1000. I have no idea what my cam is though as this was a car I bought with no info in regards to most of its upgrades. Any suggestions for me when driving it? It’s been such an issue that it completely stalls to the point I get stuck on the side of the road or in a parking lot for quite some time
That's no good my friend. Its always tough when you are dealing with mystery parts. Are you sure you car is mechanically sound in every other way? If not I would start there before getting into changing/"tweaking" things like you idle etc. I have a lot of videos on my channel speaking about idle issues and how to fix them 👍
Man, my biggest pet peeve is a wire and old connections only making the problem sometimes while I'm trying to tune the carburetor or do something else. And you got five different things going on and can't figure out what's messing what up lol. I've had a wire mess me up for 6 months. Having a wire I have to wiggle now to work. I'm going to try to fix. Definitely need more electronicle wiring knowledge
I Have the same exact problem with my cammed 5litre Ford fairmont au in New Zealand, really embarrassing at traffic lights and often doesn’t start again until I roll it and slam it into park I think this is because of a bad starter
I’m also having trouble with it very violently jolting, bassically cutting power on and off while driving until I give it more or less gas I’m assuming it’s something to do with the cam too
Oh man, that sucks…
Sounds like you need a good tune if it’s stalling out downshifting
Nice Fox 👍
thank you
I think it's the steering while your at idle or just getting down to it. Its stressing the engine just enough at those low rpm's.
Sorry, I didn’t read all the comments… what engine management system are you working with, stock or aftermarket? I’ve had serious issues with stock ECU’s in the past with many “bolt on’s,” and now I’m trying a Terminator X because I’m told that’s what I need with my 408 and heavily modified.
No worries. I am still using the stock A9L with a customs tune 👍
Running a B cam with my Gt40/Explorer set up. The worst part is the low speed bucking I get. I just put a video up on my channel.
Yep, same here pal 😂
had a 2008 with HR cams and SC'r, didn't know if it was going to take off like a bat out of hell or stall leaving a red light, hated it. thought it was more an issue with the addition of the SC'r.
Yeah buddy - its not all bad but some are definitely worse then others
An informative video, watch this video Kasl very informative about a Fox Body Mustang with same issues and problems with drivability, all tuned out with proper dashpot tuning....trust me and give it a watch...
Awesome video on cam life. But first fuck ya on more about the mags! Your cam is gold. I had a Ecam in my last stang and it wanted nothing to do with any RPM under 2500. Oh yup wanted to stall out at all the wrong times. I never let anyone drive it for that reason. I think the gurus at Leech Motosports have a way to tune it out. They got Brew2l's cammed car dialed in.
Hahahaha - the magazine haul is pure gold buddy! Also thanks for the advice. I have also heard great things about the folks at Leech. At this point I'm not sure if it could get much "better," and in all honesty, I'm probably trying to turn a 9.9 into a 10 😂👍
@@KASLCustoms I agree that thing runs wicked!
@@stephenroberts7816 Thanks buddy!
My foxbody like to stall at low rpm I saw you said you talked about that in another video does anyone know what video he is referring to I really need to watch it it would be a big help I’m really stumped

Been chasing this issue with my car for a year. 274hr cam with a Megasquirt ecu. Can't get it to idle nice below like 900 rpm
Yup - Foxbody life bud!
Great video just where your seat belt man
Ive owned my 91 emerald green coupe for over 20 years and when i put a cam in it i noticed when i would come to a sudden stop the car would stall. My dad being a mechanic for over 40 years grabs a copperhead bb from his bb gun and removes the vacuum hose to the egr and stuffs in in the there. Problem solved ha never had another stalling issue.
Hahahaha old school mechanics!!
Great video bro my gt likes to run like a banchee my dad built the car and I know he bought the motor from ford racing and told me it made power at 2500 rpm I know it’s aluminum head roller but that’s it
Very nice bud! Is it a 5 spd or an auto?
@@KASLCustoms stick now if was a automatic but dad crashed the 87 and it became stick donner…
Ok gotcha
I just cammed a 5.0 and it’s stalled twice when starting up. I don’t mind….I mean most people can’t even drive manual nowadays haha. Plus you know why it stalled, might be embarrassing, but you know why it happened. Mine grinds 98% of the time going into 3rd gear, but I know it’s because it needs an adjustment lol
nice day out
Could you just add a vacuum canister and see if that helps? That's what I would try.
Yes, you could
HI Gary. OK, regarding the coupe, have you given any more thought to trying an A9P computer? It might be interesting to see how much difference it makes. As for the cam in the Vert, you say you're giving it to your mom. What does she want, a lumpy idle or driveability that she doesn't have to worry about? The small Ford letter cams are pretty drivable and have a small amount of chop. Maybe talk to TIP and Brew2L and Foxcast, see what they think. This is just me and my misguided thinking, which is inherently flawed, but I'm sure a good solution is out there somewhere. Anyway, as always, thanks. Bill
Hey buddy! Yes, I have been thinking about the A9P you mentioned a while back. I really like the theory you have one this. If anything, mine and your misguided thinking makes us a match made in heaven! 😂. You also bring up a very good point about my mom... She loves a lumpy idle but drivability will be key
@@KASLCustoms I'm pleased you didn't take offense to my comment. I've built a lot of engines over the years and the biggest thing I've learned is to make sure the end user is happy with the result. My wife is a fan of fast cars but she would never put up with the issues that come with a lumpy cam. I'd love it but I want to keep the car so she can enjoy driving it as much as I do. That's the sole reason I left the cam alone. It sticks in in the back of my questionable memory that the speed density cams are a little more aggressive but still eminently drivable. Just because I've curious about, well, pretty much everything, I'm going to do some research into cams and what not. If I stumble across anything earth shattering, you'll be the second to know. Thanks. Bill.
Awesome - sounds good sir! Thank you
I can say when ford designed the 5.0HO and was shooting for TQ they really killed it. I know the part selection to build TQ in an engine How in the hell did they get so much low end TQ in a little engine with a tiny 3" stroke?? My 95 5.0 even with 2.73 gears has tractor type low rpm TQ. There's a road I have to turn onto going home it's very very steep and I can turn onto that road going around 30mph and I can chug up that hill in 3rd gear turning 1100rpm all the way up without any bucking just blub blub all the way up, I've found on secondary roads I can chug around in 3rd almost like a one speed trans. I will miss that a bit when I mod the engine but I'm also used to driving temperamental cammed vehicals, imo switching up to a 3.55 gear when I do the C.H.I. swap will help significantly and where I daily it in warm weather I'm trying so hard to force myself to be conservative with the heads and cam, I don't hot rod everywhere just drive with just get on it a bit from stops now n then not all the time and I'm still think go with the afr 185s heads even tho im sure for drivability I'll be happier with the 165s because there little better choice, I think people make more of a thing about runner size to s certain amount I really don't think that 20cc difference would make a huge difference...?
Lol . Actually, my car loops out a lot . I have 94GT yeap and cammed top end built lower stock . Nothing sounds better than a push rod motor . I named my car Cybil, lol . She acts up now and then . 2 stroke driving hits the nail on the head .
How much better is the explorer manifold than the stock one? I have an Australian model 97 Fairmont with the same intake as the stock one on the fox body. Also putting gt40p heads so curious to know the benefits of the explorer manifold
It's a nice upgrade over stock for sure. It flows less then the aftermarket options but better then stock 👍
