Im new to the diesel family and was just wondering what are some signs of bad injectors. What got me curious was i was at a stop sign and started out slow and decided to floor it to see what would happen. I noticed as it took off it blew some black smoke and suddenly smelled some fuel. Are these signs of bad injectors? I know it idles just fine and runs great.

fill out your sig. man so we no whats done to your truck.. Do you have a tune on it? balance rates can be checked by efi live, edge cts and a few others...
06 lbz 138,000 miles all stock. It doesnt smoke at all unless i floor it and still its not much smoke. I was wondering if they all do that or if that smoke is a indication of a bad injector or just dont worry about it at all.
Black smoke is OK. White/blue smoke is not good. Dealer or pretty much anyone with a handheld tuner can check your balance rates for you. +/- 4.0 i believe is the acceptable variance.
Personally I don't think you have a whole lot to worry about but I would check them to be sure. If your truck runs funny or feels under powered a common neglected easy solution is to change the fuel filter.

LBZs dont really have that many issues with injectors. Almost sounds like you have a small tune in the ECM. If its running good, leave it alone.
Thats good to know. After seeing what it cost to replace all eight injectors kinda got me wondering about mine.
