02 lancer oz rrm intercooled turbo. A few days ago i got caught i a storm and ran through some deep water which caused my car to jerk when i started to hit boost. So i took my filter and mas of and dried the little bit of water that was in them. After that my car seemed to run fine for a day or two about 30miles. Until yesterday i got about 1 mile from mu house i hit some rail road tracks and my car stalled and wouldn't start back up. So i towed it home and looked at a few things. Still nothing, until the next day i tried to start it again and nothing until i gave it somr gas and then it started. It would run fine until it came to normal idle and then it would spudder from the exhaust and would sound rough under the hood but the rpm needle in the car doesn't jump stays normal. If i rev it for a few sec i will smoth out sor a few sec and then run rough again. I tried to drive it and it stalled before i got out of my drive way. And would barley stay running after that. Until about a half hour later if you start it it'll run like before alittle rough. If some has any info please help. thanks
