engine. When I start it, the engine instantly revs to around 2 - 2.5k rpms (way high) for about 5 seconds, then settles to around 500 (a little low from what I was told). When it's cold, it will usually stall if I even look at the gas pedal. After it warms up, it accelerates without hesitation.
While approaching a stop, and I let off the accelerator, it continues to run at around 1.5 - 2k rpms till I've made a complete stop, then chugs back down to 500 rpms, at the cost of major wear on the brake pads, and a bit of worry. There are no odd noises coming from the fuel pump. It does this cold and/or warm.
The plugs, wires, rotor, distributor cap, air filter, fuel filter, and fuel pressure regulator have all been changed. MASS sensor has been cleaned, along with all sensors connected to the intake plenum (new gaskets) and the air intake assembly. Starts quicker, but other than that there is no change.
It has been recommended to me to get a new idle air control sensor. Could that possibly be the cause of my rpm control problems? Or is it something else?
have the same problem?
