My engine vibrates well driving up hills then the RMP shoots up to 3 RPM then idles high till I get to level ground and drive for 2-5 kms before it starts idling normally. I have already changed the fuel filter, fuel pump, spark plugs&wires, distributer cap&rotor, coil, throttle position sensor and O2 sensor bank 1 sensor 1. No improvement after all changes. Why would that be?
have the same problem?
