So back in March of 2006 I posted this thread:
Should my truck sound like this?
http://www.dieselplace.com/forum/showthread.php?t=70076
I didn't really get a consensus as to whether something was wrong with my truck or not. I didn't really want to spend another $80 for the dealership to tell me nothing was wrong with it again, so I lived with it for another year and a half. During that time, my wife bought another chevy from a different dealership. Unfortunately, we've had to have that vehicle in the shop for quite a bit, but I've really been impressed with the service rep. Just for grins, and the fact that the noise was really starting to bother me, I took it in to have them check it out. I've got to mention that I've also got a predator that I use to monitor the balance rates. 3 injectors have always tended to be high -4 ~ -6. The last time I checked though, I found -7 and -10 on those three.
The dealership had it for a day and called me back later saying that they didn't find anything. I calmly said okay, I will be back tomorrow morning and I want the shop foreman to ride with me and explain exactly what this noise is that I hear all the time.
The next morning, I show up around 9:00am, but my service rep and the foreman are not in the office so I wait. From behind me outside the bay doors, I hear my truck pass. Believe me, I can ID this truck just from the sound. The foreman and the service rep jump out and confirm that as of this morning they found the that 3 injectors were bad.
5 days in the shop later, I have 3 new injectors. My truck purrs like the day it came off of the lot. I'm pretty sure I have more passing power on the freeway. It's like a new truck again. While I was there, I also confirmed that my injectors have another 101k miles worth of warranty.
Interestingly enough, the five original injectors have always been low, +/- <1 while in park, while the new injectors are -2 already. Is that normal?
The moral of this story seems to be that you really have to raise a stink to get these injectors changed :)
