My car keeps stalling whenever I start it up, once the engine is cold or warm, whenever I start it I always have to rev it for like five minutes until it is warm before it will throttle without stalling. My cold start valve is working and my spark plugs are new, vacuum lines are fine, it will throttle fine once operating temperature is reached.
I have a lot of white smoke from the exhaust when I rev it or accelerate. How do I fix it?

Hello,

It sounds like you have a blown head gasket which creates the white smoke and the oxygen sensor codes, Please check out this article to get more info on how to check for that.

This would also make it stall when cold, please check it out and get back to me.
