I had left to go camping over a 4 day weekend and left my jeep in the driveway. I came back and it started fine, after a few min of warming up i heard loud crackling under the hood. I turned it off and had my mechanic friend listen to it. after a few min it had gone away. then it had done so again the next day when I started it up. My friend said that moisture may have gotten under my distributor cap (due to the rain) and caused a short, but he was baffled that it didn't misfire. Does this sound common or could there be a short somewhere else? 2.5l 4cyl by the way.
