Misfiring

[ZZROCOOL]

2003 D2 127000miles

accelerating around somebody on the highway the other day (lots of hard rain all day) and felt the truck start to "stumble" Check engine light came on

1300
0304
0307
0300

I have done the wires in the last 18 months (didnt use magnacore)
plugs in the last 24 months.

If I reset the CEL it will come back on with the same codes.

ideas?

Sorry, I have been occupied with other work...

I would start with new plugs and check your air filter/MAF to make sure they are not dirty and are sealed.
