    2003 gtx sc intermittent loss of no 2 cylinder

    I have a 2003 gtx sc with no power and 5500 revs,
    If I disconnect the no 2 cylinder the sound and revs stay the same, I have changed the spark plugs no difference and have checked all the connections to no avail.
    anyone had the same problem, any fixes thanks

    Check the compression in the cylinders. If that is good you might have a bad coil.

    Disconnecting the coil pack wont result in any motor sound change at idle, you need to have the BUDS hooked up to see what is going on, I would assume you have a bad Coil pack or valve train problem, what is your max RPM? how many hours on motor? Compression wont tell you everything on a 4 stroke, only that there is a problem. If the compression is low in that clyinder it could be a result of bad piston, or valve problems. What made you think there is a problem with the No 2 clyinder in the first place?

    problem fixed

    thanks fellas problem was dud coil on no two. I removed the coil and moved to other cylinder which then didn't run, point of interest these skis will start and run on one cylinder so it makes it easy to find a bad coil, I took ski out today and works a treat
