    High Idle - 2200rpm

    Hi all,

    Recently had an ecu fail and have since had it repaired. I have just put it on the ski and it is now idling at 2200 rpm, previously it was 1800rpm. Any thoughts? I pulled the flame arrestor from from the manifold while this ecu was being fixed. Could this cause a higher idle?

    Im guessing that the easiest fix would be to take it down to a dealer to hook it up to buds and adjust the idle, unless the idle vale is shot.

    Pete.

    Check for an air leak on the inlet manifold if you have had it all off to do the flame arrester - Just a thought.

    Your idle will always be slightly higher out of water that when the craft is in water as there is no resistance on the prop.

    Reset your TPS.

    I think getting the TPS reset is the logical answer. Given the ecu has been apart i think the values need to be reset. I never had the ski idle this high out of the water, maybe 1900 but never over 2000.

    Thanks guys

    According to the workshop manual, resetting the TPS also resets the IAC within the ECU. Hopefully the IAC valve itself is not faulty.

    Cheers

    If the TPS doesn't do it unplug and remove the IAV, stick your pinky in the hole and move it up and down until you can get the ski idling where it belongs and hold it. If it stays there you got yourself a bad IAV. Do NOT leave it plugged in when you remove it or it will come apart trying to unscrew all the way

    reset TPS if that does not fix it, then you more then likely have a vacumn leak on manifold from when you removed it.

    TPS needs to be reset. You can take it down to the dealer, or do it yourself with the CandooPro system
