I have a 1996 Pontiac Grand Prix SE and every once in awhile when I am driving the RPMs would be around 2000 then drops suddenly like my engine is not getting any fuel. The car acts like I am tryin to drive a manual stick shift for the first time when it does it but never stalls and the service engine light does not kick on. The fuel pump and fuel filter are new was just replaced not to long ago.
When the FRP was checked there was no fuel present.
Also the fuel pump makes a loud whinning noise which according to the auto parts store some fuel pumps do that. Is that true?
Would the MAP Sensor be causing this problem or would it be the fuel pump relay thats causing this?
have the same problem?
