kiltedcelt Posted March 23, 2010 Share Posted March 23, 2010 I have a misfire on cyl. 1 ( engine code P0301 ), but as the post title says, only in wet weather. The engine stumbles and misses but only until the engine warms up completely, then it runs fine. I can erase the code and then the problem will come back the next time it rains or we get a really wet humid snow storm. The car had new wires about 2 years ago, a new coil pack, new plugs just about a year ago, and a new knock sensor around the same time. Any guesses as to what would be causing this? I'm hoping it's not some kind of lose ground wire or something equally frustrating to look for. Link to comment Share on other sites More sharing options...
