Primary TPS, high idle issue.

[fastfun]

I just get at this thread ) Bike was running all right but there came in a first issue with throttle responding while shifting down.So I mean, while riding and between kicking down the gear pedal and clutching I hit the throttle a bit each time but now there was a short silence while hitting the throttle a bit. Stopping the bike,idling was singing around,up and down.,AFR round 9.8 while dynojet autotune fuel targettrim is round 14.0 at idling. However,AFR is sticking around 9.8.
No airleaking hoses, TB ok etc. did checking.
Also did checking the primary TPS voltage, 0.60 looks like ok and as for some time already I did remove the secondary blades and idle stepper there was no issue. till now.
Now I did set the voltage at 0.66 and the engine is running ok at idling.But AFR still hanging around 9.8 at idling, till 10/15% throttle during riding the bike. After 15 % the AFR suddenly increasing at 13/14,about fueltargettrim values.

Do you have an opinion about this issue ? Toss the TPS?

Toss it and get a NEW one. The MAP and barometric pressure sensors can do this too. A bad connection can do this too. Mine started acting up after I installed the RamAir. It was a royal pain. Eventually it went away. Still get the high idle hiccups sometimes. Can't wait to have Scott reinstall the tune when we meet at MV.[/QUOTE]

Tnx. Because of the sc the bike doesn't have the map and barometric sensors anymore.No bad connections too. What possibly caused the issue is the main 30A fuse fromwhich its plastic housing,not the metal, gets melting in due time. ...

Just got my 05 back from the dealer with a new primary TPS. Idle was annoying before at 1600, now worse at 2500. Comes down in about 20 seconds of not touching throttle. Taking it back tomorrow, not getting good feeling about it reading these replies.

Old thread... same problems. There are two others with the same "idle running wild" issue with active threads.

Look at it you should be able to tell if its a new one or not. No tools just look at it.
