This is a problem Id hoped I had fixed when i did a new intake install. Car starts and wants to quit when its cold you have to give it gas to keep it going. when its starts running on its own it wants to die when you turn the steering wheel or hit the brakes.

This problem started when i put a new cam in a long time ago. Its managable once the car gets warmed up it runs great. I did a lot of things to it lately includding new headers, rockers, intake, TB and i removed the A/C and all the AIR/EGR stuff. Car still is doing the same thing. Im wondering what could cause a car to do this? Could it be a bad oil pan seal or something that is the only thing I havent redone? Let me know if anyone has experienced the same type of problem.

 

i had a simmilar problem it came down to that i had to much preload on my lifters with affected my vacuum at idle what caused my car to go into cold start same proplems you had check that and what size cam can affect vacuum too little can put you into cold start as well

 

I replaced my rockers also

 

Have you checked the coolant temp sensor in the water pump housing? That will affect cold start, if it isn't working correctly.

Have you ever had the engine scanned, for things like MAP, TPS, IAC counts, etc?
