6.0 stuttering and smoke

2004 6.0 is stuttering upon accelerating at stop lights. Or when in overdrive and starting up a hill, or under a load hauling a trailer etc. It's sounds like the EGR again, but I've cleaned it again, put on new O-rings. Last time I cleaned it, it wasn't that dirty and it wasn't stuck. But I cleaned again and reinstalled. Also, it might be me, but it seems as though it gets worse when fuel is low. If it's not EGR what else can it be? Also it smokes a little when this happens as well. Most of the time it's black smoke, but it has been white also. Just a big puff an then I'm good to go.

if you pull on the pintle of the egr, it should spring right back into its bore. sometimes the shaft of the pintle binds internally = bad egr valve. Your problem sounds like a fuel pressure or faulty injector(s)

I've heard that the EGR cooler can become clogged as well. Would this cause the engine to bog down also?

What can happen is carbon builds up in the egr cooler/intake mainfold, and the carbon can eventually flake off and momentarily hang a valve. That is something that would happen intermittently, and would be impossible to duplicate at will, and would probably happen once /week-month. If your truck does it all the time, i would suspect fuel injector/fuel pressure/FICM MPower. If pump whines, it would be worth pulling the filter from the framerail pump and seeing if the outer-layer has "wrinkles" in it, causing a restriction.

I change fuel filters often, but I can pull it out and check. Truck has 161 K miles, how long do injectors normally last? And how would one determine which one is faulty?

You have an injector going out.

See if you can get a code reader on there ASAP.

I'd limit your driving too...

So injector failure... Will a code reader tell which one is going out?? And can you accelerate out of a bad injector? It's only a low RPMs when this happens.

Yes and Yes, initially.

You'll have cylinder contribution codes in whatever cylinder it is.

Ok, let me see if I can get ahold of one. I'll let you know what I find out.

Auto parts stores usually check codes for free...

I'm telling you this from experience, I had the same thing happen to mine right after I bought it.

I hadn't even made a payment on it yet!
