I wish someone would respond to you, mine is doing the exact same stuff. I think i might just have to call the good ole' Pontiac dealer Monday, when it gets electrical I don't trust the local mechanic. I was wondering in mine if it was the computer, I don't get why all the lights would come on if not. I have heard throughout the years, if you get a new computer, to buy it from the dealer as opposed to napa, cause the car companies update the computers instead of just cleaning them up.
