Its been having a problem for about the last month. It only happens on occasion. Sometimes it runs perfectly smooth for days with no problem. Then out of nowhere, it runs rough at stops when in gear. The RPM gos up and down erratically surging and will sometimes stall. It always starts right back up though. It almost seems to be a vacuum leak but I thought I'd get some opinion first. No CEL either. Temperature is normal as well.

It seems to happen more often under load at stops. Its never done it while cruising even at low RPMs. Only happens at stops. In fact, sometimes it does it then I hit the gas to go and it smooths right out like nothing is wrong.

Any idea's or suggestions to check???

Sell it because it didnt have much oil in it.....

Dunno could be a vacuum leak I dont think its that though it would rough idle all the time and die.

Fuel filter possibly? Could be clogged up....

Does it have an EGR valve?

take it to a shop and put it on the computer.....could be plugs or catalytic converters might have some bad o2 sensors

I would start by changing the fuel filter, then work you way to the EGR Valve. My 07 Dakota used to do that all of the time. I ended up finding out that the fuel pump was bad.

This truck has a "non servicable" fuel filter. That sucks. Thats usually an easy thing to replace on cars. The truck is pushing 70k miles so its probably due. It looks like thats a dealer thing.

Maybe a bad throttle position sensor.

id replace/check the O2 sensors. my jeep had a problem a few months ago that sounds like the problem you're having, and it was the O2 sensors that were causing the A/F ratio to go up and down.
