    Stx12f Stalling

    Ok, Here's What Is Happening. Ski Starts And Runs Fine, However About Half The Time You Open The Throttle And Let It Off Real Quick It Dies. Always Starts Right Back Up. Have Changed The Idle Control Valve And Still No Change. Any Ideas, Maybe A Sensor Bad? Any Input Will Be Appreciated......steve

    Any chance you have bad fuel? Did it just start doing this or has it been acting up since you brought it out of winter storage?

    I chased that demon for months and for me a valve clearance adjustment is what finally solved the stalling when letting off the throttle.

    You're welcome. There are 3 things that can cause it. One you already tried and the other besides the valve clearance is the TPS (throttle position sensor) on the throttle body. There is a test procedure for that in the manual though.
