Car runs rough in rain. I"ve noticed that my car runs really rough in the rain. My ses light blinks at me and I noticed my car sounds like it's going to die but never does, while driving it doesn't seem bad but when i'm idle it sits there and lopes at me as if i have a cam, which i do not have one in. I've changed out spark plugs, spark plug wires, cleaned out maf, changed o2 sensors, and still no luck. Any suggestions?

This only happens when it rains though, would that still be the issue your saying? I talked to some other guys that had this issue and they are saying it is my O2 sensor harness might be getting wet. Hoping that is it.

Look for a cracked spark plug wire or a partially
seated boot; a little water can turn open circuit
into a shunt path for spark current. Open the hood
and mist one plug / wire / coil at a time and see
if you can cause a miss.

next time you wash your car, see if any water dripped down the cowl panel and onto the engine
i have a similar problem, only i get really bad clutch chatter, almost enough to vibrate the car apart

As mentioned, probably a bad plug wire. Also make sure a wire isn't touching a header/exhaust manifold pipe. Possibly a cracked spark plug.
