ok to start off with the exhaust. Does anyone exhaust not shoot out exhaust correctly like instead of a steady flow when u put ur hand behind it. Like it shoots like puff puff know what im saying? Sometimes when i sit at a place or get on it just a lil i come to a stop and white smoke comes out the exhaust. My rpms jump up and down a lot when at idle. I cleaned out the idle air control valve...didnt work. My boost gauge when at vaccum moves a lil up and down when the rpm do to. Also i have stock spark plugs in gapped to the right specs. Could that cause all of this? I pulled one out yesterday it had a white electrode and the rings were like blackish. Im running stock injectors on 10 psi. So what could cause all these problems. Im hoping that my head gasket is not broken. Hope it is something simple to fix. Give me some opinions on all this please.

 

Hate to say it...but sounds like a head gasket to me. Check your coolant and see if you have oil in it.

 

Err... head gasket. Bet there's coolant and oil mixed.

 

Dang that just ruined my day
