The check engine light comes on in the rain or snow. The light will go out after a few days. I guess after the car has completely dried put. The car runs fine otherwise. Anyone have any ideas?
10 to 1, it's the coil pack.
Go out in the dark.. open the hood, start the car, spray
a light mist of water around the coil pack. If you see sparks,
you got your culprit. (could be the sparkplug wires too, so
spray over them as well).
Here's what to do then.
