Warrenty work
Posted earlier of 2016 ZO6 (9700 mi), with Code PO300/PO50D. Modifications few, Hallcraft Air, Borla X, and Mamo TB. Have it at dealer, who recommends replacing all 8 injectors. was told due to cost GM had to inspect the vehicle. Has been done, dealer said they should have reply on Monday after GM reviews it. All of this sound normal? should I have a concern.? It seems strange that they could not isolate the problem injector, (PO301 thru PO308), and replace. Thanks

In your case the history file may show different results leading to the fuel injector diagnosis.
Why don't you ask them to print out the history file for you?

Thanks
Dealer said that GM would get back today. When I had it checked at Auto Zone it was Random Misfire Detected and Cold Start Rough Idle. There has never been an indication of White smoke, quite the opposite Black smoke and a couple backfires. i'll wait till I hear from them today, just felt it strange an inspection of the vehicle to OK from GM. Been a pretty "Babied" 9700 miles with a few "Get on its". After driving it it seemed to clear up, but was back next morning.

It will be interesting to hear the outcome of your inspection to see if the mods affect warranty coverage. Was the inspection done by a GM rep or the dealership? This may answer a lot of questions and speculation about what mods can be done to a car and still retain coverage.
