Cam, this problem has to do with a leaking input manifold gasket. The vehicle is a 1993 Pontiac Grand Prix GTP with a 3.4 dual overhead cam engine. The engine RPM surges up and down when idling an lack of power when accelerating. I took it in for an analysis, the result indicated the intake manifold gasket was leaking. Any quick fix possibilities for this problem? No oil or water leaks involved.
