Folks:
Replaced my Yukon's (2008 Denali 6.2) water pump. It was failing big time but I caught it before damage occurred.
HOWEVER....
....in the process I didn't realize there were 6 bolts to the water pump; thought there were 4. So when it didn't come off the block at 4, I decide to take a rubber hammer and gently tap it. Thinking the gaskets might be holding it tight. Hit it once...nothing. Took a second swing and on my downward motion grazed the left side of the throttle body with the hammer.. the part that houses the plastic components. I "ping" went off as one of the 6 brackets that secures that plastic part to the metal throttle body flew off. I thought noting of it...UNTIL I filled it with new fluid and started the motor. It no longer holds a steady idle. Sometimes jumps as high as 2K and then back down to 800. When driving, it will accelerate on its own as well. Not fun....
Has anyone damaged their throttle body or had throttle issues that were caused by a bad throttle body? I get no codes, don't think it is the mass air flow sensor since we didn't bother it.
I went ahead and ordered a replacement; I just HOPE that is what went wrong and something larger isn't at play.
Thoughts?
