Re: 08 GMC Hybrid engine replacement
The idle was rough like one cylinder missing. My wife normally drives it, so there possibly could have been some symptoms she missed. I simply told her the night before that it was time for an oil change, so I gave her my car in the AM.
Did not get a thorough explanation as to the cause, just something involving cylinder #1. However I was out of town for the next two weeks. I will try to get a more thorough answer.
