I got a 1990 camaro rs with 305 tbi and its started to stall out right after it starts but only does it when its warmed up and it only does it once everytime I start it when its warm. I have no idea why. Can anyone help me

 

check for codes first.

 

Even if the check engine light isn't on

 

faulty ignition module will do that and not give any codes

 

yep ,check anyway and bungy74 is right too, Also bad fuel injectors will not throw a code either.

 

you may want to check fuel pressure also before replacing any parts, many times people overlook a weak pump

 

I've heard of this!, i cant remember exactly what its called but what was described was...when you turn your car off the fuel in the lines near the motor absorb the heat from the engine (ahh its called heat soak) anyways when this happens i guess it messes with the fuel somehow not allowing it to start. I don't remember why, look up heat soak, if it only doesn't start when its hot and will then start once it cools i'd guess this is it.

 

seriously doubt its heat soak.

 

I just bought one and had the same problem. The previous owner told me it was the IAC or idle air control sensor. Then i checked the EGR and replaced lines...turns out it was the 3 dollar PCV valve my dumbass over looked.
