small kink in the cable?

 

next time it does it i will remove throttlle cable cover at throttle body & make sure it is released. thanks for suggestion!

 

ok got it to act up & removed throttle cable cover at throttle body & found when removeing cover that fuel was dripping out. check throttle plate & is up against throttle stop screw. it is definitely not the cable. any one ever seen fuel in there? also noticed when idleing that there is little bit of fuel leaking past throttle shaft. normal? now it is idleing 1700 rpm & it will not lower. also origanally it seemed like it happened after it was pressure washed. any more ideas would be nice.

 

No that is not normal. It sounds like your throttle shaft bushings are worn out but on a 2011 model? WOW. I had one that was worn out, but it never leaked fuel. The problem it did cause, was you could not keep the TPS adjusted properly because the throttle shaft had so much slop in it. One of the symptoms of that was an erratic high idle, mostly only after the engine was fully warmed up and the ECU was running on the normal operating temperature map, not the cold running map. Also make sure you have plenty of play in your throttle cable, like an 1/8" at the pedal or that will cause a high idle.

 

OH...one more thing to check. I have had this one happen to me also. The throttle plate screws apparently loosened up just enough that the throttle plate slid over and was rubbing the bore of the body, and not closing completely every time. This was intermittent also as sometimes it would fully close. Loosened the screws more and it actually centered itself, then retightened screws.

 

jeff thanks for your replies i will remove throttle body & check throttle plate to see if centered. also on throttle cable adjustment i removed throttle cable cover & throttle plate is touching set screw & you can push throttle shaft ip against set screw by hand & idle still the same.

 

no more ideas out there?

 

ok i removed throttle cable completely & no help on idle. removed throttle body, not one spec of dirt, looked at throttle plate looks dead on center, no signs of rubbing anywhere. checked connectors on throttle body & cleaned them, removed iac sensor & cleaned throttle body. any one ever seen iac valve go bad? still have same problem any more ideas?

 

Donny,
If you know how to check your TPS volt reading with a meter you need to do that. That is just another thing to rule out. Also, did you check for slop in the throttle shaft? Can you wiggle it up and down or side to side? If there is too much play your TPS will never hold a good reading and will cause all kinds of problems, an intermittent or continuous high idle included.

 

i will look in my manual & try to test tps but yes throttle shaft has no play which it is 2011 rzr with 476 miles. i was hoping to find water in connector but all dry.

 

well tested tps & iac valve. all within specs. will assemble back together. running out of ideas!

 

Call Delta Powersports, they can probably give some info.

 

well all back together idleing 1200-1250, will take to hollister hills tomorrow, hopefully it stays this way. if problem reoccurs will drop off with mike at delta power sports. cleaned & greased every connector on rzr. will check back on subject tomorrrow. also going to frank raines on sunday.
