2002 Dodge Ram 2500
Hey everyone, I'm new to owning a Dodge/Cummins. I just got into a 2002 Ram 2500 a few weeks ago. It has 179,000 miles on it and is completely stock except for the BHAF. The thing starts and runs like a top except it has an intermittent miss at idle after it is warmed up. It idles perfectly smooth when I first start it up, but after I drive it far enough to get it up to operating temp, it has a rough idle. The goofy thing is if I shut it off and start it right back up it will idle nicely for a couple minutes and then starts acting up again. Also, if I drop the auto trans into gear it starts to idle perfectly smooth again. It doesn't take much of a load on the engine to smooth the idle out either. Sometimes turning on the headlights and stepping on the brake pedal makes the alternator work just hard enough to smooth it out. Other than that it runs amazing. I already checked the fuel pressure and it sits at about 18 when idling and drops to about 14 at 2000 RPM. I'm excited to learn from all the Cummins guys here!
