My 2002 Honda Odyssey all of a sudden started to misfire at first it was on three cylinders and then it was all six. This is what I've done so far. I've replaced all the plugs and one bad coil pack. Now my check engine light is still flashing and I'm just getting the P1399 code. I'm not sure what to check next. Right now I'm on limited income and I can't afford to put it in the shop. If anyone has any suggestions it would be appreciated.

 

I'm still having issues with my 2002 Honda Odyssey. It was suggested to me that I clean or replace my EGR valve so I cleaned it and there's no difference. Now I'mgoing to try looking into the ports on the intake. Hopefully I will figure it out soon.
