Ok, everytime it rains my car runs like crap. I really do not understand it or why. It can be colder than hell and it will run fine but after it rains and I start driving it, runs like it has half of the cylinders with-in the rpm ranges of 1500 and 3000. After it gets all warmed up it runs fine like it blows it out or something. Anyone have any suggestions?

 

Do you have an aftermarket air filter? K&N filtercharger? or similiar? You could be getting water into the engine. You might need to better shield your filter.

 

Well, I do have a K&N Filter, but it acts like that even before I drive it, I dont think that water could get there just by sitting in the rain.
