Will not rev beyond 3,500 rpm,
Why does car not rev beyond 3,500 rpm ? Acts as tho a rev-limiter is the cause, but, I've disconnect the Throttle Position Sensor and still runs the same. It would not cold start without a long cranking period while holding gas pedal half way down. I disconnected the vaccume to throttle body which allows engine to cold start without touching throttle. Still runs the same, rough idle, sometimes lightly backfiring, as when driving, before the automatic gets ready to shift and hits 3,500 rpms the engine shuts down to whr u have yo ley off gas pedal to allow it to shift and every gear you have to let off again at 3,500 rpm. The engine itself, runs same as discribed. How can i correct this?
