So we got some pretty heavy rain here. My car is parked outside, and this morning I went to the car and started it up. I let it run and it seemed ok for a car that hadnt warmed up fully yet. I drove it out of my block and it was really sluggish. Limping around the neighborhood. I knew something wasn't right so I slowly made my way home. Parked, and as soon as I got there I threw a CEL light. Pulled the code with my AP and..

Cylinder 1 misfire detected (p0301)
Cylinder 2 misfire detected (p0302)
Cylinder 3 misfire detected (p0303)
Cylinder 4 misfire detected (p0304)
And
???????????

First time I've ever seen this. Help.

I recall that you run a short ram intake correct?

Probably got wet, and got some water in the intake. I would say let it dry really well and all should be okay.

I have the subaru SPT SRI (with the heat shield) and I got the same exact codes when I drove through a 2-foot deep puddle on the freeway during WOT.

Dry everything out and it should be fine.

Short ram. So the filter is in the engine bay, nothing close to the ground. That's for the responses. I'll just let the car dry out if this rain ever stops.

Keep in mind that dew can form in your MAf housing due to the 100% humidity, rain, and cool weather outside.

Some times the crack in the hood lines up with the filter.
Hope your good to go now
