    04 STX 15F idles high varying between 1800-2500.

    Hey Guys. Just picked up an 04 STXF 15 with 77 hours on it. Ran great when I first rode it. Went 62mph no probs. Now when i came back to shore it idled at about 3mph in water (too quick)
    On trailer it idles now at about between 1800-2500 rpm It varies up and down ie .Not consistent at all and wont go back down to a consistent 1250 rpm.

    It had probably a little old gas in it when I got it. I put 12 gallons 93 in it and it run great and still does- Just has too high an idle!.
    Any idea what wil cause this on the 04 15F guys.Any help is appreciated. Dont really want to go and buy 4 different parts to eliminate!
    Thankyou
    TPS?
    ICS?
    Throttle body?
    dirty gas?

    Mine did something like that when it was new, it was something to do with the smart steer. Bad sensor in the handlebars if I remember correctly. Its an 04.

    Dunno if you guys are still on this forum, but did you resolve the high idle issue? My '04 15F seems to hang a little above idle when the throttle is chopped.... then it takes a few taps or fiddling with the throttle lever to get it to settle and drop to normal idle... but no stalling or anything else wrong besides this hanging idle. I hav a feeling it might be the start steering.. but what part of it would be the culprit? Maybe the sensor? I think it uses magnets or something.

    Anyone else have this issue?
