I have a stumble in the engine when stopped at a light or sitting in a parking space. It's worse when the AC is on, but seems to happen even when it is off. It feels like maybe the idle is too low, but I haven't a clue if this is normal for the truck?? Confused None of my other cars/trucks have had this.

If it's not normal I'll run it to the dealer for a looksee...

I believe it's normal for these trucks. Mine's always done that.

Mine does this too a bit, although it is erratic. It feels like, as you say, a marginally low idle. I have the climate control on mine and the kids fiddle with the rear controls all the time, so it's hard to correlate, but I think it is just the extra load from the system cycling on and off. It does sometimes go away on its own while at a stop light and other times the idle will dip while stationary for no other reason I can think of.

Ok, well at least it's not just me. I'll mention it in passing on the first service and see what they say.

Thanks for the feedback guys! Cool

Curious if anybody found out anything about this. Mine seems to be getting more noticeable.

Earlier this week I took mine in for the idle-relearn and it did make a slight difference. The tech told me new engine mounts might help so they are putting that in tomorrow. When they called this morning to tell me the arts are in, they said the tech called Nissan about the issue and they said to bump the RPMs on the idle up a little. I guess 500 at a red light is a little low.

He told me the Pathfinders and Frontiers all run a little rough, but mine was worse than most that he has seen. Maybe this will make it better.

One thing I've noticed is it matters what gas I use. Around here (southern NM) all of the Fina stations became Alon. I have found that I get worse rough idle and some cold start stumble if I use that brand. I've been paying attention to it for a while and I'm sure it's not coincidental.
