Well, I have driven it every day since the 16th with no issues. And, today, it happened again. RPMs up to 1500 when it should be idling, only happens after it has been driven. If I turn it off, then start it up, everything is fine. Then drive it around, revs up. Checked the vacuum line that had come loose previously, it is fine. Guess I need to take off the TB and reseat it.

Pain in my rear!
