I am guessing that since the Hanes manual said that if the spark plugs look like they are burning hot that it could indicate that I could possibly have a Manifold vacuum leak, well since my car has been stalling and idleing rough I could agree?.. But my Question is where? Could it be where the plenum bolts to the manifold or where the manifold bolts up to the engine? Or should I replace both gaskets? I don't really here any leaks with the naked ear but, who knows?

 

could be anywhere, best thing to do is take gumout or starter fluid and spray it around the intake, if the engine speeds up then you found your leak.

 

Good Idea never thought of that, Thanks
