When we hit about 25 MPH or more the car revs then stops, revs then stops, revs then stops. ND it only does this when we hit the gas not while at idle. Just replaced the air flow sensor and 2 others and it is still doing it. Adjusted the rim idle; tried everything I know how to do.

  • If you are in the US can goto Autozone and they will hook up a tool to give you the diagnostic trouble codes or DTC's. If you have those troublecodes someone here will be able to more effectively assist you in fixing the issue potentially. Sep 14 '16 at 3:02
