started car today and it cranked a little slow but once it started it sounded like a diesel. held idle fine for about 4 min while i let it warm up. but after i gave it gas then let off it would stall out unless i gave it more fuel. its a mtx. any ideas?

 

Sounds like you have some vacuum leaks.

 

replaced the coil which was def bad. but the problem is now still there but on a smaller scale and is not constant. i think its only happening when the car has warmed up. and ideas?

 

Maybe, but I am not 100% on this. There are a few folks that complain about this same thing you are saying. (Heating up then dieing.) The cam or crank sensor was to blame but, I don't remember which sensor it actualy was.
