I need to check as to when the plugs/wires were changed. Regarding the fuel filter. That was replaced about 3K ago.
I don't think it could be something that simple. I know that the dealers "supposedly" went through everything with their equipment (diagnostics and all), and couldn't find anything.
As I was searching through the forums, I noticed that someone else mentioned disconnecting the battery, and then reconnecting it? Any truth in that matter?
