Looks like you fixed it. Over 25 years straight of owning fox bodies, I've found the ignition module is often the culprit. They get really hot mounted on the dizzy. So much so, that on my 91 LX I've relocated it with a homemade heatsink. No problems since on this car.
I just wanted to say thank you for the video. I've been having problems with hot starts for a while and this cured it! This is video explained it very well and easy to follow!
This is the best explanation ive seen of this yet. Done the procedure a few times now but always come back for a refresh! Thanks! Works with the X3Z PCM I have!
@Cliffdodger I had just got it back together and put in the car when I did this. It struggled with the cam and heads for some reason. It's only an E303.
Aw man, this right here is the best idle reset video on youtube! Glade you mentioned your channel on junkyard doggs most recent video. Subbed 🤙🏼 keep em coming!! (:
I've seen where if you are having trouble in this area but with a surging idle and getting egr codes, you can change out the coolant temperature sensor and it will clear it up.
A stock A9L computer is set to 672rpm's for a manual and 672 idle and 624 in drive with an automatic so setting your idle at 50rpm's your IAC wont even be used for maintaining idle.....It will be all throttle blade or Tom Brady screw as you call it... The way I set the idle is I set my idle to 600 rpm's which gives 72 rpm's of idle drop for the IAC to cover and for the adaptives to learn alot quicker.......If you set the idle to where it barely idles then the idle will swing that low................... Another thing about setting the idle at 600 if you have a manual and you granny shift the idle wont drop much below 600............. Instead of twisting the distributor to advance timing and gain power I make myself an octane rod thats is tad shorter than the rod that sets and locks the halls effect trigger in place...........I usually go with one thats roughly 2 degrees advanced..
In addition, I suggest disconnecting the spout connector while the idle air solenoid is disconnected. This keeps the ecm from manipulating ignition timing, that way it's not working against you.
I think the trick is getting it set on the base idle 725 or lower. We all contribute the stalling to low idle so we try to set it higher to compensate but the computer will shut out the control if it cant control the idle low enough to learn the bottom drop of the idle witch causes the stall. Im going to test this theory tomorrow ive got a 92 doing the exact same thing heck even the a/c will stall it at idle. Thanks for the vid it helped a lot.
@scottsinfl I have a Trick Flow stage 2 that I may put it. I've seen a lot of people complain about idle issues with the E303. I also have a Comp Cams 274HR as well... but it's in a 351 on my engine stand.
I have an issue with cold starts. It rough idles for about 3 minutes and then it clears up. I have changed the coolant sensor and purchased the pcv kit and air charge temp sensor but haven’t taken it to the mechanic. I will definitely try this after replacing the act, pcv kit, and a new c&l 76mm maf. 😊
@@89G I think it’s because I powder coated the timing chain cover and didn’t grind the powder off where it actually contacts the block around all the bolt holes so the starter isn’t properly grounded. It’s the only thing that actually makes sense since it does it with a brand new battery. Great video and your instructions were crystal clear.
Here you go. IMO, this is the best way to check for vacuum leaks. Let me know if you have any questions or suggestions. th-cam.com/video/vsOO36yaj90/w-d-xo.html
I am SO sorry! TH-cam didn't tell me that they had held your comment for review. This was published in one of the Motorsport publications years ago. This method has always worked very well for me.
Not yet. I wanted made well so I put an order in to Japan. I know some Toyota’s are made in Mexico and I’ve heard horror stories. Where was your Yaris made?
Do you have your fuel line going to vacuum tree or the intake itself... trying to see if I did something wrong... I deleted the egr & all the smog & tad/tab sencors...
I will go look in the morning. I don't remember where I tapped in. I do know that it needs to be a direct connection though - not ran the the TAD and TAB.
Having this exact issue with my 91….except I have 24lb injectors BUT…I don’t think my maf is the issue could be unsure going to try this reset see what happens before I order a $250 maf sensor
@@joekloiber887 Joe, I need to apologize. YT never sent me the notification that you had responded. I was meaning do you still have the stock MAF? I put the C&L on my 89 with a matching 24 lb. calibration tube.
I want to adjust my tps and my timing. But I can’t start these steps until my misfiring situation is figured out. I don’t want to get my 302 to operating temps while it’s misfiring
@@89G None as I checked and plugged what I found. When I installed a new intake gasket. I did here that a car with a Cam would not run with it unplugged. It might have a cam because it looks like it was drag raced at some point in its life because its got subframe connectors, rear tubular control arms, headers & h-pipe. Also It appears to emissions & Oxygen sensors deleted as well.
@@alvaropimentel779 In the intake tube, between the throttle body and the air cleaner, you will have a sensor with 4 wires if you have mass air. If you don't have a sensor, it's speed density. Most 88's did not come with it. Only California Emissions equipped cars had it. Let me know if you need anymore help. The mass air cars are a lot easier to play with overall.
Did you have to swap the PCM?
Nope, it still has the A3M in it right now. This procedure got it to idle with that A3M computer.

@@89G so I’ve seen
@@alexchadbourne maybe we can get yours in a video or two. I wonder how it would do with some paint correction?
Do I have to touch the timing at all, I’d rather not until a later date. Ty for the informative video.
@YELLOW08Z06 as long as its not way off, you should be fine. If it's already within 10 to 14 btdc, that's perfect.

Ill try this tonight. When the engine is cold it start and stall immediately. Try again and itll try to die.

When do you set the timing on the motor? Before all of this or after?
Great question! I set it beforehand on this car However, if it won't run long enough to set it, I just get it close, then recheck after.
Do you have to reset the timing of the car just idles higher than normal
@@89G I changed my spark plugs cap and rotor spark plug wires and now my stang idles higher than normal
Are you in Colorado
I'm next door in Utah.
Does this idle reset work with speed density?
Yes, it should as long as you don't have vacuum leaks.
My 89 won't stay running no matter how many turns I give the idle screw any ideas I'd hate to just start throwing parts at it.

@@89G Yes harness still there but the bungs appear to be welded in ! But it's still running. But runs rough.
Do you adjust timing before or after?
I adjust it first, then recheck. Sometimes all you can do is get it close when it wants to die.
