hey guys i have been having problems my car after warms up idles like crap rough. and when i punch it it hesitates and then goes and the whole time floored it is smoking like a whitish color smoke. also when i punch it it doesnt want to go into the next gear it bounces off rev limiter and then goes or i have to let off of it. it is an ls1 automatic any answers thanks guys

 

sounds like you have an intake manifold leak or one of the head gaskets is blown check ur oil and see if there is any type of antifreeze / oil mixture

 

LS1 intake manifold is dry so that's out.
Sounds like a head gasket.
Have a shop check the coolant for combustion gasses and check the oil for coolant.

 

oil is fine not milky anything esle

 

Vaccum leak somewhere?

 

it doesnt do it all the time though i am stumped on this

 

also where could it be leaking vacum from
