Low Idle symptom of Bad TPS?

Just curious. Sled is running good other than that. It seems to idle fine when I first start it, then it dips down to 950-1000 rpms after it warms up. Wondering why? I don't remember it doing that until after the top end rebuild.
The dealer said they checked it, but they probably did that with the digital wrench or their tool, which I heard isn't as accurate.

I had the same thing while riding in wy with 4ft fresh, ran awesome exepect for the low idle. I got it home thawed it and it idles fine prehaps throttle bodies were iced up or something. My dealer like yours said it was nothing.. Idles fine now, but heading back out to elevation next week and we will see if it does it again!

Try taking the pipe temp probe out and clean it off.

Maybe with Brake Cleaner?

And a cotton rag with some fingernail work. Under 5 minute job that can't hurt.

Make sure your throttle bodies are clean. As they get dirty, idle speed will decrease.
