Just bought this GTX. Runs great except for when you just give a little throttle - about 2000 to 2200 RPM. It acts like you are applying throttle and immediately relaxing throttle in 1 second intervals. After you give more throttle to take off, it seems to run fine. Fresh fuel and oil. I did notice that the idle RPM in water is about 1750 on the meter. According to my Seadoo shop manual, it should be 1500?100 RPM. It also states that the TPS (throttle position sensor) is the main factor in how this machine runs and can only be adjusted using an MPEM computer which I can't afford to buy.
Is there any way to adjust the idle without hooking the MPEM up to a computer at a dealer?
I'm hoping that the high RPM is putting a little too much oil into the burn causing the sputter and I can make the adjustment at home without dealer cost.
Thanks for any help!
