2002 dodge ram 1500 4.7 misfire code p305, p0303

Asked by Dec 27, 2014 at 01:56 PM

Question type: Maintenance & Repair

I have a dodge ram 1500 4.7 with codes p0305, p0303 misfire codes. I have replaced all
the spark plugs and coils 3 and 5. And the p0305 engine code came back on so I replace
cylinder 5 coil again and again the p0305 engine code came on. Any ideas of what could
be the problem?

Is that a direct coil on boot on plug type application? If so it probably a bad plug boot. Remove coil again. Pull boot off of plug. Inspect boot carefully for carbon tracking. It will be a gray sooty looking spot on the boot where it's allowing the spark to jump out.
