Well, I got a check engine light and intermittent VSA light last week. I took it to the dealer and they found rodents had chewed the wiring on one of the solenoids that control the engine valves. (If I'd known what was wrong I could have fixed it myself.) Fortunately, it didn't fry the engine control computer. Now, I have to keep baited traps in my garage and check daily for deceased mice. Already offed two of the critters. Jon
