probe having trouble accelerating

I have a 94 probe gt, when the engine is cold, and i accelerate, it runs like a normal pgt would, but as soon as it warms up, when i accelerate the car will shake, and not accelerate too well. expecially at lower rpm's. any one know what this can be? i was thinking a bad fuel/air mix, but my buddy said maybe there was a miss fire, but if this were true, wouldn't it always do it, not just when it is warmed up? ok thanks, before this happend i ran a can of "sea foam" through, but i ran all of that out, and filled up on a 1/8 of a tank. any ideas???

Could be the HT leads breaking down.

hey, is this bad??? and how do i fix it? i know a little about car's but im a first gen, trying to learn it all. thx

Tricky one.. Runs good while cold..runs crappy when it's warmed up..

Was it doing the same thing before you tried the 'sea foam'? Or did that just make it worse?

well i used the sea foam, two times, but at the same time i had a new distributer put in. im thinking it's related to that, cause right when i got it back, it started doing this. i took it to the dealership and they are saying that it is related to the air intake. i put a differn't air temperature sensor on, and it is still doing it. i've cleaned out the throttle body, inspected the hell out of my aftermarket air intake. and have spent countless hours checking for a problem, im going to put on the stock air intake then take it back to the mechanic's. but i don't see why this matter's. i have all new plugs and wires... i just don't know. it seems like all the mechanic's are trying to cheat me cause im a 17 year old kid. it pisses the hell outta me, cause in 9 months i am going into the army special forces, and putting my life in grave danger so those f***ing mechanic's are safe. and i diddn't have my mommy or daddy buy my car, i work 35 hrs a week flipping burgers. i guess this is a little off topic but ohh well. any way, yea i think im going to look into getting a differn't car.
thanks

It could be a problem with the aftermarket intake..Thing about this is that when the car is stone cold the computer works off of very basic settings. after it gets warmed up? It uses the sensors to run the engine. If the stock intake was replaced with an aftermarket? There's a chance that either something was disturbed...prehaps the air flow was changed slightly so it's not working with the sensors.. I'm not sure it it uses it or not..but if that uses a mass air flow sensor, and it's not sending a true reading to the computer? That could create problems.

What the heck...I'd give it a shot with the old stock intake and see what happens?
