    Low and Surging RPMs in Idle HELP!

    Bought a reman engine Aug of last year and has not ran properly since. In the water the idle RPM goes from 650 to 1100.... On the trailer idle RPMs vary from 1100-1300. If I adjust the screw idle screw while in the water there is little to no affect but once on the trailer runs up to 3300 RPMs.. Help! I have already rpleace the APS and the TPS sensor. Took it to a shop for the TPS but the guy has a CanDoo Pro and doesn't really appear to know what he is doing with it.

    What could be cause the low RPM surge? Ski runs great other than idle speed.
