I have a 2006 Ford Fusion. We just changed the valve cover gasket and spark plugs. We started my car and it took a while to start up and doesn't sound right at all. It almost seems like it's going to shut off as I left it running. I have the wrench light and check engine light on now. The wrenk light says throttle control/transmission and says it illuminates when a power train fault has been detected to take it to a dealer asap. Did we do something wrong when we changed the valve gasket cover and plugs?
Help please!
