runs like crap when cold

[1995greenstang]

anyone with a 94-95 have issues when the car is cold mine when its cold and i get on it, it starts loading up kinda like the spark is cutting out but when its hot it runs fine any ideas?

Pull codes.

Post up more specific symptoms. Very plain terminology is fine. For instance, I have no idea what the statement about loading up after spark loss would feel like. When I lose spark, it misses and can't get out of its own way.

If you have mods, create a sig so everyone knows what you've got.

have a gt40p swap stock intake.mac.iac cleaned maf sensor wasnt that
its breaking up at high rpm when its cold doesnt do it when its hot after running for a while i would reference it to rev limiter feel. does it at about 2500 up when its cold but stops after it heats up have custom chip burned mac full headers h pipe have changed the distributor 3 times beginning to think its the distributor again not sure. its runs very well just cant get on it when its cold

I doubt it's the PIP if it only happens when cold.

Have you checked the ECT calibration? I check them at room temp and then again at operating temps.

no havent checked it dont have a voltage meter to check it just trying to get an idea of what it could be ran 13.47 at the track but the car was hot trying to run it cold see how much better it does

My car does the same thing as yours, when mine gets up to operating temperature it's like it transforms into a completely different engine because it runs ands sounds like a beast but while warming up it runs and sounds like crap. I would also like to know the fix for this

One needs to do a little leg work on these cars to narrow things down. Otherwise, lots of time and money are wasted throwing parts at a fix.
