Check for vacuum leaks, this will cause rough running cold and can make other components read out of their range and set the check engine light.

You might also check the coils. There are six. One for each plug. My Tribute would shake and sputter each time it rained. Bad coil on cycl #5. After the car warmed and the coil dried out, it ran great.
