I have a 3.9l 2003 100K Auto Van and have issues with is running on less than 6 cylinders. I understand the 3.9 is the same as in the Dakota so I figured I'd try here.

Get codes
p0303
p0304
p0300

I have replaced

Wires, cap, rotor, coil, oil, oil filter, flushed cooling system and cleaned IAC, TB and PCV.

First code I got was p0303 for I moved fuel injector #3 to #5 spot than got code p0304 and p0300.

Thread in the van section is here:

Thanks for any help.
