I stopped in at a local dealer (whom I thought had a good reputation) to have my injectors checked (smoke at idle, rough idle)...they said I had to schedule it. I can't be without a truck, so I had to make some arrangements. I call them back, explained the situation and asked if I could wait while they check it. The "service consultant" got pissy with me and said "NO, you can't wait...its at least a three hour job to check injectors on that truck". I said (knowing full well the procedure) "Oh, what does that test consist of?". Stealer "You have to tear the motor down, pull the return lines on each injector and see how much fuel they return into a beaker". Me (still playing dumb)"Ok, I thought you just hooked it up to a computer. Stealer "NO, it requires engine teardown, if I don't do it this way GM won't pay me...and once you commit to the test you commit to injector replacement". I said "Then forget about checking them". He just hung up.
I called another dealer and they were good folks over the phone, said they will do it while I wait and that it takes about a half hour. I'm taking it there.
