P0300 Code along with a check engine light and misfiring after washing engine today..

its most likely the plug wires if not the coil pack. They are the only two things effected by water that do what you describe. I wouldn't be touching them while it is running. The have a good jolt, and pulling them while running will cause more problems, codes, etc.

Well 120 dollars later (for a coil pack) and the car is still missing on acceleration and the engine light is still blinking.....

I don't want to pour all kinds of money replacing everything in this car until i hit it correctly...........
