2002Sport is on a distinguished road
Default Rough Idle when first started

I have a 2002 Ram 1500 with a 5.9L 360. When I first start the truck after sitting, say overnight, it starts fine, but after a few minutes it begins to idle rough and sounds like its almost going to stall. After a minute or two of this, it begins idling fine and runs fine. This happens every time the truck has been sitting for more than a couple hours. If I attempt to drive during this "bad idle" phase, it sputters, has loss of power, and sounds like its backfiring. I never have any problems while driving the truck, only during this cold startup.

The only why I can avoid this situation is if i start the truck, let it run for a minute, turn it off and start it up again. Then, the problem goes away. Any thoughts?

I have the same thing, and so do others. It's like its transitioning from the high idle when its cold down to the regular idle. Dunno why, sounds like it has a really lopey cam. I wouldn't worry too much about it.

2002Sport, did you ever get this figured out? My '99 sport is doing the exact same thing. Starts fine, idles fine for about 60 seconds, then starts chugging. Although, I'm able to drive mine just fine, only the idle and only when cold.
I JUST had my plenum gasket replaced so it must be something to do with the TB or the idle air sensor thingy. I asked the guy to clean the TB while it was off, maybe he forgot.

Hmm, mine seemed to work itself out. Idling fine now. Might have been the Shell fuel.

Mine does something similar to this, but, it didn't matter what temp or anything. Just anytime the truck was at idle, it would start chugging, sounding like a lopey cam, and if I let it go long enough, it would stall out, unless I revved it up or something.

So, I got underneath the truck and unplugged the o2 sensor, and my truck runs great now...no problems since. So, I'm getting a new o2 sensor. I asked the dodge dealer and they told me that "if unplugging it fixes the problem, its your problem."

Once I get a new o2, I'll let you guys know whether it fixed it or not.

That's interesting and good info on the O2 sensor. But you weren't getting a code on the sensor???

Older OBDII systems won't pick up faults like the newer stuff will.

I had a bad EGR that did that on my old dodge and 1 other time it was the cap and rotor. On my HEMI it needed to be re flashed and that fixed it, not sure if this helps you

I remember some of that. My '95 ImpalaSS didn't flash too many codes but it seemed I was always fixing something on that car.
