I know throttlebodies dont but I dont know about the sensors. Its possible however I doubt it. Did you clean you MAF and Filter? That could have an effect on the RPMs. The running rich seams a little weird to me though. I feel like the sensor would be what would make it rich so a tune may be needed to fix it, but I didnt think they needed it. Could be something weird with sensor going on.

Check everything all looks good. Sounds like a monster and runs like a Kenyan. RPM is still messed up though. It's looks like a tune is needed...

Nope. Only when it stalled. P0316. Miss fire on start (first 1000 revs). Reset it and it never happened again. That was a few days ago. Found a vacuum leak. Resetting it one more time and we shall see what happens.
