    1994 Ski Nautique PCM 351 Pro Boss - Idle Speed RPM is too High.!

    Hi.

    Im having this issue already an year or something. The speed and RPM (1000-1100) is too high for the idle torque. As it said in PCM manual, its should be somewhere 600-650 in forward gear, which is far law than my boat has.

    Someone advised me to check the torque regulator thing. Now, the regulator is maximally released, but the torque is still high. Lately, I noticed, that very slightly, but still, the torque is playing. At the start of the skiing session, when starting acceleration, the engine is like stalling for a millisecond, but after runs very good.

    Ive changed plugs last summer. Also, Ive change idle air control valve, because, when I was stating engine, the torque was going up and getting down very very slowly. Sometimes it never decreased and I had to shut down and restart the engine.

    Unfortunatley, Im not in USA to call the technician, who will come and sort out everything I have to do it by myself, thats why I'll appreciate your help.

    Thanks
Working...
