So far I love my 6.0

[Firstdiesel6.0]

Bought an 03 excursion with a 6.0 and 140k miles. Question is, I've had it a month and a half and noticed occasionally it starts to sputter every now and then. I don't last long but that fact that it does worries me. This is the first diesel I've owned. I have heard horror stories about th 6.0 but have read on here guys that love and sware by them. Anyway any ideas what the sputtering could me? It will do it cold or warm. Have some other minor things I've found wrong, glad I got the extended warranty just encase.

I would check the FICM voltage first.

Have you changed the fuel filters? Is the maintenance up to date?

[Firstdiesel6.0]

Well bought it from a dealer and they claimed they had but again I don't trust the dealers all that much so I plan on going through it again and replacing filters etc. It is all stock but one day when I can afford head studs I will start building on the power. Would filters cause it to seep just a little under power on take offs? It could be me but when I take off from say a stop light I put the peddle down and it seems like it takes just a little longer to get going before it puts you back in your seat. Sorry if I sound ignorant on diesels but its my first and I know pretty much almost nothing on mechanics. I have slowly been reading and studying upand won't to really be a diesel head but have a way to go.

The fact it takes a second to really "take off" is due to turbo lag. It needs to build boost, as soon as it does power is there. Until then, they are a bit sluggish.

Makes sence, I've head the turbos on these are prone to failure do you recommend I replace this turbo asap since it has 140k? Also I will change the filters asap and see if that helps. What about getting a diagnostic check done it, that should tell me things shouldn't it?

[dazdillenger]

No, a bit of lag is perfectly normal. As for turbo failures, they're actually not very common at all. If I were you, I'd do a full service-oil/filter, both fuel filters, and some fuel system treatment. Don't be afraid to get on it every now and again-the main reason these turbos get gummed up is because people drive them like old ladies. Running the VGT through its entire range of motion keeps things freed up.

Thank you for all the advice, I will do the things you suggested and see how it goes from there. I know forsure they changed the oils but filters I doubt it. Again thanks for everything and sorry bout the type o's I'm using my IPhone. Gotta get up early. Will let you know how things go. Again thanks

Don't just mash the pedal from a stop like you do a gasser. Roll into it and it will respond much better.

I agree completely. Get yourself some good oil and fuel filters from here. Get yourself some good 5W-40 oil from here. Finally get yourself a few bottles of DK and run the heck out of it for a few weeks. Then re-assess the situation. Good luck!

I'd also recommend ASAP you get yourself an Edge Insight CT or CTS because it could save your a$$ if things start to go bad. You can catch them early.
