TPS reset in Maine

[DandyChiggins]

Looking for someone in Maine that can reset the TPS in my 2004 rfi. Local dealers refuse.

I've done many resets of the TPS. I've installed different computers without resetting the TPS with no issues. Is there something specific you are having a problem with?

I have a 2003 gti rfi. It was not running when I got it. The obvious problem then was a shredded rotary valve. Rebuilt motor and reinstalled. It runs but idles poorly and will stall if not giving throttle. On the water it acts the same way. If you can get it to rev up it will take off and go. Let it return to idle and it will stall out. Checked the rotary timing multiple times as well as a bunch of other stuff. Suspecting tps and would like to rule that out.
Fun fact, I am nearly positive this is the same ski that was discussed on this forum a few years back, which I think you may have offered some advice on back then: ***03 GTI LE RFI NO Start got spark, compression, fuel... WTH***

Did you set the idle for 1500 RPM on the water? Think about it a second. Most RFI idle setting is for 1500 on the water so when connected the TPI setting is pretty close on all the skis. I agree with ruling it out and setting it properly but that has never solved a problem for me. I've replaced computers, TPS, throttle bodies, and none of it really mattered. When it isn't running correctly there is a problem. Next time you take it out to the water remove the seat and touch all the electrical fittings and plugs as you ride the ski. I found a hot plug one time and after trouble shooting replaced the computer. I have spares so it is pretty cheap and easy for me to do a swap. I think the RFI is the most difficult ski to troubleshoot. I spent a lot of time camped out with my head in the engine compartment. LOL Check your grounds. Did you test the raves for holding pressure? If the raves are partially open the engine will not rev off idle.

Thanks for the reply. It really won’t idle on its own in or out of the water. I’ve tried disconnecting the raves to make sure they are shut but no change, I have another coil, swapped that and no change. I’ve ohmed out all the sensors listed in the manual, checked the grounds, checked voltage while running, made sure the rotary valve was set correctly and all the o rings in place around the cover, etc. do you think it’s worth putting a new tps on it and seeing if there is any difference? I still can’t find anyone local to zero it out. Thanks

Absolutely do not replace the TPS. Did you physically adjust the idle on the throttle body? TPS has nothing to do with idle speed. Idle speed is a hard stop on the throttle body, vertical screw (allen head) and they get frozen quite often because no one ever moves them.
