Changed Oil...spits sputters..please help

[7.3ghost]

Hope someone can give me some advice. My dad just bought a 03 supercrew with the 6.0 yesterday. Only has 100k miles on it. Truck ran perfectly yesterday coming home with it. Drove 70 miles no problem. Got up this morning and changed oil. Went to go to store and once we got on highway it seemed just fine and then out of nowhere it started spitin and spuddering kind of like lack of fuel? Would just do it every now and then. Runs fine taking it easy, but if you get on it and put a load on motor it starts the cutting out. At one point I could hear turbo seem like it was fluctuating up and down in rpms....maybe just me imagining things. Anyway other than a fuel injector acting up after a oil change can an oil change effect the turbo in any way on these 6.0's?

Yea oil lubes the bearings. You changed the oil filter right? And what about the fuel filters?

hadnt changed the fuel yet. Which I know doing that will make it sputter. I let the truck sit for awhile, went back out and drove it again. Didnt act up any. Got on it hard and ran great. Who knows....maybe some trash or air pushed through the injectors

Well since the trbo variaable vanes are activated by oil presssure there may have been trash/sludge gumming up the plunger/piston in the control valve. The valve is electricaly controled but it is oil pressure that moves the piston in the valve.

I had the same thing happen with mine when i first got it. If the truck sat for a while most likely the turbo is bad. Dont let them give you a rebuilt one. I had mine replaced with a rebuilt one and it went bad right away. Also it may be as simple as cleaning the egr valve. Its always a good idea to do a egr block off, or delete it completely.

what kind of oil did you use???

[7.3ghost]

what I meant by sat for awhile is that after driving truck and it was cutting out.....I came back home and let truck sit for an hour or so. Then went back out and drove it again. No problems at all after that. Ran just fine. In fact seemed like a totally different truck. Ran like a scalded dog.
