Mis-Fire on 2005 TB

[levigilbert]

I have a 2005 TB 4WD w/ 60k on it. My girl friend took it through a car wash and the check engine light came on and it started running rough. She took it to a dealer and they ran the scan and said the number one cylinder is misfiring. They said they checked the plugs, wires & coil and all are OK. Now they are doing a compression check on that cylinder. I have a hard time believing there is anything wrong with the cylinder, rings, piston or valves. Does anyone have any advice?

What engine?
Does it have a dist cap?
A good dealer trained tech should be able to find it.
I would suspect something got wet.
Give it time to dry out?

Tips on going to a Dealer.

Ask that only a factory certified gasoline engine performance specialist work on your car.
Not all dealerships are concerned with how repairs are dispatched, and not all dealership techs bother to take advantage of the training offered by factory (the vast majority of which is paid training). If the dealer is uncooperative, ask for your money back and call around for a dealer that will accommodate you.
