Just bought a 1988 LX and currently dealing with the car starting up but shutting off. This is exactly what I was looking for, got some things I can check for now! Thanks, subbed!
Awesome video!! Great to cover the basics and starting from scratch. Sometimes it's overwhelming when you get your fox and you have no clue where to start. Your videos always help me narrow down problems and help quickly troubleshoot.
Most of the time MAF is the issue, give it a clean with a special electronics can cleaner and you'll be good, but some times mustang can have a lot of random issues including misfires from the plugs, also speaking of spark plugs make sure the cables are routed good and when I say routed good, just make sure cables don't touch any hot metal surface and don't let them touch each other. Last year I fixed an issue to a friend's sn95 it was backfiring too bad, so I noticed the cables of the right head were hanging all together right behind the alternator, so I separated with 4 ties and took em away form behind the alternator, and the idle changed completely and of course the mustang turned into a beast instantly 💪🏻😎
Thank you for this I’ve been waiting for this mechanic to get mine running for almost a year and now you’ve made me wanna just work on the damn thing myself 👍.
Myself and others (I'm certian), super enjoy vids like this, make no mistake, this vid.. has helped me already feel better about Mustang shopping. As matter of fact, if u ever have the chance, maybe add some content about new fox body shopping. What to avoid, what to look for. I've been in the market for maybe a month, I haven't purchased many cars at all, so any inside tips are welcomed. Another reason I stumbled on your channel. Thanks.
Ive been involved with these cars for the last 30 years, its ALWAYS a 50 cent part that goes out on these cars,you only realize that after you have spent 500 on parts, lol, funny thing,back in the day we never called them Foxbodies,Five Ohs were their main name,here recently i installed a brand new 347 on my 91,it was running like crap,driving me crazy and testing my patience,turned out the brand new regulator i had put on it i guess had been sitting on the shelf for a few years and it was stuck inside (the gauge indicated pressure was fine) took a vaccum pump to it and i guess that loosened it up, runs like a charm now. Several years ago on my 89, it would die with no warning all the time,when i would hit the brakes and i was listening to the radio it would cut out completely,about a month thru this ordeal i was working on it afterhours at my work and this guy was walking by and said "hey man, you car was arcing when you were trying to start it,i was like where?? back around the driver side of the engine he said,took a look and that ground strap that goes from the body to the head was green with verdigris and gunk,50 cents for a ground strap later and the car ran like a Rolex. I have worked on many cars and i have seen ground straps hanging loose dragging on the ground and the car had zero problems, these cars do not like broken ground straps AT ALL, also always check your hoses,vacuum leaks are the bane of the cars also,on both of my cars i have clamps everywhere and i mean everywhere, like you say,its always something simple.
I have a video of what I think is a broken roller lifter from my fox if you want me to send it to you somehow so you can show people what it sounds like.
Great Video B....these types were the ones that you cut your teeth on and gained you popularity. I agree, you absolutely do not need to be a rocket scientist to work on a fox, just have some motivation 👍
I learn alot in this video! I leave in Brazil and own one of the mabe 20 foxbody here. And I have to do things on my own all the time. Allways learning with you!
Got mine for free a 1988 lx 5.0 hatch it wasn’t running but i zip ties the ignition switch into place and had it running for free the same day after sitting for 9 years
Nothing negative I can say about these videos if you're new to the fox world and have not worked on them for a while this guy can steer you in the right direction. Good video. I have been doing mustangs for the last 30 years and this guy knows his stuff. If we lived in the same town I would love to do lunch with this guy and exchange tricks and tips we have accumulated over the years
Could you upload a video on how to find vacuum leaks that aren’t that visible such as in this video. Also, how to adjust emergency brake cables. Thanks in advance! I enjoy all of your educational videos.
I watch you videos to help me work on my f150 ive been redoing. Ive replaced a ton ove valves and sensor before an iacv made major improvement. Still having some bucking and stalls once shes at tem and sits
Man I ain’t going to lie I thought I was had a bad injector miss/ or fuel pump not working properly/ or clogged fuel filter.. etc.. turns out before I did any diagnosing on any of that I try to easy/dumb shi* first.. so I took off my K&N filter and held it to the sun and I couldn’t see no light😳. So I took it off and fired it up sounded different hit a lot quiker.. felt like I gained 20hp especially on the big end. My air/fuel ratio was ideal/rich.. and before it was barely ideal. That was an easy fix always do the easiest things first when troubleshooting.. time to invest in some K&N cleaner.. but I might steel Rodney’s/( 50tussin ) trick and run a boom tub out of the head light when I go to the track.. 💪🏻
Great video! But around here where I live (Vancouver, Canada) there is no $2500 car like that. Granted .... currency exchange/different location. But a quick CL search finds around here you pay a lot more than that even for a non V8 car or a roller.
Do you think the open vacuum line might go to the open vacuum port on the intake? Instead of capping them both off try plugging that vacuum line you just blocked off into the vacuum port you just blocked off. Great videos bro. When I'm waiting to buy something for mine and I've got the itch to do something to my car I watch your videos to satisfy that need to do something. Thanks!!!
Yeah I’ve done that before, made a deal with a guy on a car and went back with the ignition modular and fired the car up to drive it home....dude straight said “thanks for fixing it, think I’ll keep it now unless you want pay another $3,000 since it’s running!”
Wasn’t worth going to jail. Now I make sure to have title and keys in hand. Sometimes they get a little pissed when I fire it up and drive it off. Funniest one I did most recently was a 96’ v8 thunderbird. Stupid clean car inside and out, they wanted $400 cause it “needed a trans”. Bought it, came back with 5qts of trans fluid and drove it home and put a seal in the trans, they had let it sit for a long time and leaked most of the trans fluid out and when they tried to move it wouldn’t go in gear so they just posted it up with a bad trans.
@@20b3rotordream I had different luck, four months ago, when I got a great deal on a 91 5.0L T-Bird LX that was super clean (odometer gears were broken so it had unknown mileage). Older guy in his mid 70’s was selling it. All it needed was a power steering pump, passenger window regulator, right rear cv/axle and differential carrier bushings. Paid $1,500 and then a week later I’m discussing upgrading the parts in the AOD at my buddies transmission shop. Why? 4th gear went out. There goes another $900😩
The vacuum on the intake that you closed off with a bolt and rubber I believe connects to the plastic and rubber vacuum line you saw found on the back on the passenger side probably connects to the vacuum nipple on the back of the driver side of the intake you should connect them two together and see how it runs
Man you are good. So maybe you can help me. My car idles fine when it’s cold. Only when it gets hot it wants to surge bad. And eventually will die. X-303 cam, Windsor jr heads, 24# injectors. Every sensor replaced. I’m out of ideas
@@BREW2LFOXBODY I have a fuel pressure gauge. It stays around 39-40 psi. My buddy has a 7up mustang with around the same mods but his idles good. You met him at ford takeover by the way lol. Is it just because it’s not tuned? I wouldn’t think so. I could make that two hour trip to you lol
was on here to watch videos cause i just got a fox buttt, the spark issue at beginning just saved me from trashing my 5.4l engine in my f150. i had checked everything on it and couldnt figure it out, cant imagine watching this video a year later and figuring out the problem. i had thought it dropped a valve XD
the popcorn popping at idle at the start of the video is an lean pop misfire, fixing the the 1st leak stopped it, the hanging idle when you free rev it is another clue it still has a leak.
I would love for you to work on my car, bought my car 2 months ago in cali drove it back to Oklahoma just dont know much about it ... Would like to link up with you in a convo or email
Lol....My 93 Fox want even start with the gas needle that low....Mine's been sitting up for five months now so it's adling around 1500... if I unplug the IAC Valve it drop around 800...Going to check for that air leak right now......Thanks
AC check valve has a busted line left of screen at 6:56. My cars just crumbled the other day and it's made my car very lurchy and the idle is terrible. You can plug it off, however your AC will blow through the defrost vents when under decent throttle
Great how you are the master troubleshooting fox body’s 5.0’s awesome video once again you taught me something again thanks so much 👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏
I have a 88 Foxbody that ran great before it sat for 2 years. At idle runs very rich(black smoke from tail pipe) and sounds like it has cams. Swapped the injectors to another factory set, fuel regulator doesn’t leak fuel at the vacuum port, ran a smoke test and no leaks, blocked off the egr and same issue. Spark plugs are all fouled. New gas. If I unplug a vacuum hose, it idles better. What do you think it could be
@@ruazfast plug wires are all correct, car drives fine and doesn't sound like a misfire. Just has a "pop" at idle. Very similar to the one in the video
I’m having issues with power from the alt transferring to the battery. Have had alt and battery checked multiple times. Getting the lift picked up tomorrow and installing it myself. Hopefully make some progress on this fox.
@@BREW2LFOXBODY exactly, it will idle all day but as soon as I try to drive it it dies. I’ll have to try your suggestion. I have a busy day tomorrow for sure driving to Orlando to pick up the lift. Used the same company you did a video with your lift.
Bro I have an issue that idk how to fix, i see all your video and none of them cover it. Car doesn't run till i push it back and place the gear in 1st than after few times it runs.
I've got a 1999 Mercury Mountaineer. About 3 months ago a vacuum hose popped off under my intake. I blocked it off and started running good again. I don't hear it sucking anymore but I'm not sure what I blocked.
Great info. I purchased a crusty 93 Fobra a month or so back and this kind of info is super helpful. It's a strong running car although I'm trying to figure out why it goes lean (10-12 afr) for the first minute or so after you start it and then it goes stoic and stays nearly perfect. I'm guessing something to do with open/closed loop? I was told it needs one of the O2 sensors replaced but other than the momentary lean spell it seems great. I know nothing about the bottom end, but it has your typical B or E cam with GT40 heads, 1.7 Crane rockers and Explorer intake. Still running 19's with a matched aftermarket MAF. It was tuned by a reputable shop with a new ECM and SCT chip last November. Would the O2 sensor cause the momentary lean after startup?
@@BREW2LFOXBODY Yes, the tune is custom. I can't remember all of the parameters that were adjusted without looking at the paperwork, but it's more than a "boxed tune". The AFR is almost perfect other than it goes lean for a minute or two after startup. It will pop once or twice lightly if you accelerate during that time. (Mild acceleration, not hard or WOT) After a minute or two it goes back to 14-15 and runs great. I bought the car with the tuning already done. Ultimately I think I will get the O2 sensor replaced and see if they can go over the tune again.
Another epic video! The KISS method is the best method
Now that is how it's done, another problem finding video. It's always a vacuum leak with Foxbodys,
Love the BREW2L sign on the garage, it looks great.
Man great diag. It kills me sometimes when I can’t find some problems or small little things. I’m going keep coming back to your videos
Brew2l love the sign mounted on the front of the garage. Love the how to videos. Keep bringing them!

Cause if he took the supercharger off it was probably tuned to handle that and without it, it doesn’t function very well
