Last night I had to drive through a pretty deep puddle (up to the doors). The car had to work to push through it and the engine bucked a couple times pretty hard. I think the clutch was slipping or something. By the time I got through the puddle, the engine had thrown a code and was running pretty rough. I figured I had soaked my air filter and I might be choking the enging, so I swung into the local parts shop and bought a new one just to be safe. That didn't fix the problem though. As I drove around more, the engine began to run better and would get brief bursts of it's normal self, but would then stumble again under load. This morning I drove about 25 minutes on the highway with no problem, but once I got off onto the surface streets it missed a couple more times. It's not a constant problem, but seems to show up when the engine is having to work. I'm wondering if I have a vacuum problem. Are there any lines on the bottom of the engine that may have been affected by driving through the water? Any other ideas? I thought maybe my dizzy had gotten wet, but I think that would be more of a constant problem. I'm at a loss, any clues? Thanks

 

do you have the stock air filter, or do you have an aftermarket cold air intake?

 

did you check the code? you should do that first to tell you exactly what the problem is

 

check your wires, plugs, and other electronic crap that can get screwwed up by water.

 

pull the wires, see if you have water around the plugs
