    2010 rxt changed tb having high idle problems

    Was having all kinds of TB fault codes and limp mode, found out the TB was frozen shut from some corrosion on bearings , Got a used TB from greenhulk member and installed it today reset tps a few times and all fault codes are gone. I Stopped and started ski 4 or 5 times and reset tps a few times, most times It idled at 3500 to 3800 so I shut it down, 1 or 2 times got normal idle then when I revved it ,it revved normal but would not come back down to normal idle stayed up at 3500 ish. throttle body moves freely no sticking and all the TB codes are all gone, just having the high idle issue now.


    Could this be from a TAS acting wacky?

    I checked the TB gasket a few times to make sure it was not leaking seemed fine

    By the way this is Sams Ski AKA - XDAILY

    Remember what I told you about my TAS problem and how to test it?

    Remove both the brake lever module and TAS module, connect the brake module to the TAS connector. It will be backwards, but you can start the ski and rev it up with the lever on the module. If it idles correctly and revs up, the TAS module is bad.

    Also put it the water and run it until operating temp. Stop and restart it allowing 3mins for a full electrical shut down for the ecu to do a self learn. Do this a few times.

    Ok switched out tas with a working one fropm my ski and still the same problem with high idle, could it possibly be the ecu? the tb gets its commands from the ecu and it controls the rpms among other things correct?

    A vacuum leak in the manifold, TB gasket, or Lube port will cause a high idle...

    Yes thats the first thing I checked for on TB gasket, did not check manifold and it does not have a lube port , The thing is I can reset tps and it will start normal idle untill I give it throttle then it will only back down to 3500 rpms and stay there, acts like its sticking but it all moves freely.
