Understood, lot of items to look at. HOWEVER, all the sudden the idle is fine. WTF? I got out on a main street and got it up to about warp 5 and it got REALLY hot. Not sure what was up but I headed back to the house, and in frustration revved the crap out of it and an bunch of shrapnel hit my truck WTF???? Turns out there was a massive mud dauber wasp nest in the right silencer. Blew big chunks out and they were all over the driveway! It now idles fine and is not overheating. Not sure this was the issue but I am going with it until further notice. Fingers crossed!
