Hey Guys,
Just joined up. What a great resource of info for our trucks.
Truck- 2003 Ram 2500 5.7L / 72,000 miles. Plugs changed at around 50,000 miles with OEM. Plugs , air filters, and oil changes are only thing EVER done to engine.
What I have going on is a slight slight rough idle, almost like the smallest skip. Codes are P0300 and P0306, General misfire / Cylinder #6 misfire.
I kept meaning to troubleshoot and dig in, however, I have two toddler boys that keep me more than busy.
Anyways, decided to dig in one day and I noticed the CEL was off. I decided to check all intake hoses, change PCV, and cleaned IAT sensor. Started it up, CEL back on. Same codes. Pulled Cylinder #6 coil and plug wire. Inspected plugs and gaps. They look good. Swapped #4 and #6 coils. Started up and drove for awhile. Checked codes, now I'm getting P0304 / cylinder #4.
Should I replace all of the coils? Is this that random of a failure to where I shouldn't worry about any near term additional coil failures?
Any other ideas of what I should check? I know the problem following the coil pretty much tells the story. What I want to do is replace coils and plug wires at this point to keep it strong.
Any input is welcomed.
