    05 seadoo gtx help

    Hey everyone. I recently purchased an 05 GTX 3 passenger and have a question about the idle. When I tested the ski it idled about 3000 rpms on the trailer just fine. I thought that was normal because my jet boat idles around 3k on the trailer and then drops to 1500 in the water. Well after cleaning everything up I noticed that the throttle cable was broken where it mounts to the engine and was zip tied back on. Well I fixed that, changed the oil and threw in some fresh plugs and now it idles erratically between 1800-2400 rpms.
    I downloaded the service manual and read that the tips is not programmable by the owner and has to be reset by the dealer.... Considering this guy was cruising around with the throttle opened do you think my rough idle is because of the tps or could it be related to another issue?

    Thanks guys!

    Normal idle for a scic 4-tec is 1750-1850...or so.

    Try some fresh gas?

    It certainly wouldn't hurt to get it on buds and reset the TPS. In addition check your idle bypass valve.

    If its been sitting then fresh gas and fuel Injector cleaner.
    A plugged Injector can ruin a cylinder quick.

    Thanks guys. It has been sitting for a while, but I went ahead and pulled the fuel pump and checked the filter. Looks dirty but nothing that would cause it to run rough. Im gonna put some seafoam in and add some 93 and take it on the water today. Hopefully it clears up.
