Since the internet is crammed full of folks who like to complain...I have a good story.
I normally do all my own work, when I got my 02 Silverado it had a couple of codes, I wanted to fix it myself as the warranty only covers the lubricated stuff.
It had a MAF code and both knock sensor codes. Replaced the MAF (80 bucks) cleared the MAF code. Replaced the Knock sensors. Cleared the P0332 rear Knock sensor but not the P0327 forward Knock sensor.
So I fooled around with it awhile and couldn't get it to clear.
Took it to the local Chevy dealer and spoke with the tech, told him everything I had done and then we went for a ride. He pulled the codes went back to the dealership and an hour later he told me I need to get the wiring harness and most likely the front knock sensor because the Autozone ones have only been problems in the 6.0 trucks. NO CHARGE. I bought the stuff at the dealer and presto problem solved!
Dealership said they didn't want to charge me for something they felt I already had the answer to and they were just a second set of eyes!
That saved me the 95 dollar diagnostic fee. Awesome!
