  1. DFI is unnecessary. I'm a Service Advisor at a GM dealership and we see so many of the Ecotec motors come in with misfires and it's almost always bad injectors. Also, the bad injectors foul up the spark plugs and flood the oil with gas so now the customer needs 8 new spark plugs (no point in changing just 2 or 3) and an oil/filter change to accompany that expensive service. Good money for us especially if the vehicle is out of comprehensive warranty but it's a pain in the ass for the owners because they depend on their truck.
