    Car misfiring after it rains

    After a good rain or a on and off rainy day before my car drives for a bit it will misfire pretty bad in lower rpm's. Not exactly sure what would be causing it throwing in the rain issue. If it's dry out and everything cars fine but again with the rain it's really annoying, just not sure where I would start looking. Figure water is getting in something either electrical or who knows.

    Any ideas?

      Came across this thread, seems like hood seals, crank sensor, or possibly ignition wires, or the wiring harness itself:

              Plug wire or coil wire not seating properly?

                  Get a spray bottle that sprays real fine. Then, on a dry day, when it's not misfiring, mildly spray around the ignition system. It'll start misfiring when you hit whatever's bad.

                          Aged ignition wires can cause this. If over 10 years old replaced all of the ignition system from the coil to the head.
                          The car makes it possible, but the driver makes it happen.

                              I have a similar problem and replaced my distributer and rotor but it didn't help. I think I'll try ignition wires next and see what happens.

                                  I had the same problem. I replaced the ignition wires and it fixed it.

                                  Apparently this is a common thing. Some old guy that I was talking to at a repair shop said, that after the first rain, they always get cars coming in complaining of a mis-fire.
