Hello, im Luke but i'm asking on behalf of my mother in law who owns a 1998 pontiac grand prix, had an original problem of the car staying running once started had to keep the engine revving high in order for the car to stay running, had shop diagnosis on her problem and replaced the intake manifold gasket upper and she informed them that had been done recently, only to be told that there are two ( 2 ) upper and lower and the lower had been replaced, well her car now has a very rough idle and hard vibrations and a noise that someone told her sounds like sticky or bad lifters. Is that her problem and how can it be fixed? Or is there another issue with the car?
disperate son in law
