On some models a faulty Idle Air Control (IAC) valve can cause an engine surge at idle and set a Check Engine Light (MIL). Replacing the faulty IAC valve will commonly correct this problem.

    Started with engine surging at idle. Then, while in driving in lower gear, the engine stays at higher rpms and does not shift smoothly (jumpy). After a period, engine light came on and VTM light also. More breaking power needed to slow vehicle and some bucking was noted.

    Also had a high idle and hard shift from park to drive or reverse. Replaced the IAC. Fairly easy to do.
