Well, here we go again.
I had a large amount of exhaust smoke on heavy acceleration or if I let the truck sit for a number of days. Went in and they found 3 injectors bad. 3 weeks later waiting on parts they repaired it and sent me on my way. The smoke is back on heavy acceleration. Am I being overly sensitive to this and shouldn't worry or should I head back to the GMC dealer and have him look at the remaining injectors. The truck has 32K on it and doesn't tow too often. I am looking at getting a camper and I am concerned about engine damage under heavy load. Any ideas or input would be great.

Check your service receipt. I believe they are supposed to replace all 8 injectors no matter how many are bad.
