My dad's 94 V-6 is having some problems. It smokes, kind of blueish in color. It smells like gasoline. It also misfires and bucks while driving. He just got done changing the head gaskets and put on rebuilt cylinder heads, but it didn't fix the problem. Anyone know what could cause this? Thanks.
 
sounds like a very bad vacuum leak. any codes. what does the coolant and oil look like. get some starter fluid(ether) and spray on the intake's gasket mating surfaces and all vacuum hoses while it is running. if it revvs up then there is a leak somewhere.
