My wife called today. Anyone have any thoughts? She backed out of the driveway, went forward to the stop sign. Everything was fine. When it was clear, she stepped on the gas and the engine revved without going into gear and going forward. Then she took her foot on the gas (I guess) and tried it again and it started to go. Anyone have any thoughts? It's the second time this has happened in 1 week. I've not had this happen to me when I'm driving.
