Help - MPV 02 - Misfire engine 4, 5, 6
 

Hi,

I got an MPV 02, V6. After parking the car at the airport for almost 2 weeks, the engine suddenly lost a lot of power. The max I can drive is 10 mph now. The codes I got from the reader are P0304, P0305, P0306. Changing all 6 spark plugs and boots did not help. Not sure what else I can do. Really appreciate any help.

One more note is that during the time the car parked at the airport, there was a big snow storm and heavy rain. Not sure if this is a contributing factor.

Thanks,
Kim
