88 stang stalling

Run the codes. '88's don't have a CEL. Could help narrow down what is wrong

Do a vacuum test. Since you don't know what cam is it in, hard for us to say that's the cause.


Does it only stall when you step on the brakes? At what RPM? near idle? Could have a vacuum leak or faulty booster.

You'll get a code 21 (coolant sensor) if you try to pull the codes with the car cold. You need to warm it up fully before running the test and the 21 should go away

Code 24 is the same thing. If the air temp is under 40 degrees, you may see this code. Let engine warm up and try it again.

82 is smog pump...won't affect how car runs

Code 12 means your idle may not be set correctly. Might want to perform the idle reset procedure. Basically unplug the IAC and start car, set the minimum idle using the throttle body screw to just about where the car barely runs. Then unplug the batt for 30 mins to reset the computer. This will also clear the codes, so you will want to run them again to see if you took care of the code 21, 24 and 12 anyway.

Code 44 and 94 are also smog related..no effect on how car will run.

So, set your idle, reset computer, let car warm up fully and run your codes again. See what goes away.

You could get the 21 and 24 again when the car is fully warmed up...in which case i'd put a multimeter across them and see if the resistance spec is in range. If not, replace.

Also, get some carb cleaner and spray around the engine bay for vac leaks. Your idle will climb if there is one present.

Also, hook a vacuum gauge up and see what you have for vac readings at idle and 2000 RPM
