Howdy. I got caught in a flash flood in my 2010 caravan 3.3l V6. I took the spark plugs off and forced the water out of the engine. I put in new spark plugs and wires. The van misfires mainly when going over the 30 mph mark, or if I turn the AC on. It was showing codes p0300 p0305 and p0452 at this time. I replaced the purge celinoid. Now it has an extra code pO443. Any ideas. I was hoping that doing something in the EVAP system would solve the misfires.
