2004 Dodge Ram 2500 5.9 Cummins quad cab long bed (early 04, std output model)

215,000 miles. I've owned it since 196ish thousand. Been a great truck, pulls my toy hauler out to the dunes no problem, gets great fuel economy compared to the Hemi truck I sold when I bought this.

Running an 8k mile OCI, change the fuel filter out at the same time. Air filter is new. No blow-by, like, nothing. Doesn't overheat.

No haze, small puft of black smoke when I fire it up. I can get an extended crank if I don't wait for the light to go out, hot or cold. If I wait for the light it fires right up.

This misfire issue is pretty new, and the seat of my pants tells me it's lost a bit of pep. When stop and throw it in park or neutral that's when it really acts up, but with some load on it, it usually doesn't lope the idle like that, but it has. Truck shakes a good bit when it's acting up, and I swear I can hear a fuel knock in there.

In the video AC is off, idling in park. No CEL, no stored codes.

 

Put a new set of Bosch stock injectors in, tubes, and fuel lines. Not a bad job, took a few hours. Runs so good now. That might be the injectors being fresh, or the lack of weight from having spent all my money. But who knows.

 

tips look clean... 2 suggestions,

1st - consider running 8oz of Dex3/Mercon ATF with 24 oz of TW3C 2 stroke oil in the fuel from time to time (I do every other tank).

2nd - Consider running hot shots stiction eliminator in the oil every oil change.
