My truck is beyond the 7 year, 200000 mile injector warranty allowed by GM (in service 10/02) and it has been a sweet baby so far! I love it! ...At 113K I'm starting to notice escessive blue smoke and a slight reduction in my fuel economy. I watch it pretty close. I am guessing one or more injectors are getting iffy. I do a lot of camper & boat hauling between TN to AL coast. I need to understand how injectors fail out and will they likely shut me down on the highway if one fails completely? Is it time to just bite the bullet and replace all injectors? I'm not a serious mechanic so its gonna be a big tab item for me!

Any advice welcomed! Boat hauling/fishing season starts next month!

:help

We first noticed it when we had a sluggishness in the throttle, we never saw smoke.. That lasted for about 1 month. Then the "crap" started to roll downhill from there on out

I got two days warning... started to get hard to start, then no start at all.

See we never had that either. Our problem was wacked out. We first had a code after getting diesel at a truck stop. It was something stupid. Had to do with fuel pressure, but not the p0093 code. We opened the fuel cap and retightened it and it went away. Then it started getting bad. SES getting on the highway and then doing anything, but no hardstarts, and no 'non' starting.

A month later we has diesel in the oil, but never before that. When I finally laid her to rest I was having a horrible idle.

I guess everyone has a different problem.

So...do you typically replace inectors as they die or do the whole set?

I'd do the whole set if I were gonna do it. Might as well.

If money is tight, you can replace only one bank, if the other bank is still showing good. Heck last year I pull mine apart to replace just 1, but guess what project I am in the middle of right now I would highly suggest doing all 8 though. I know it is going to be expensive, but it is cheaper in the long run, then tearing back apart again:drink
