Looking 2 diagnose injectors
I have a 2001 duramax and it's been to the dealership 4 times. The first time was because I had major injector failure flooding the engine with diesel fuel. In that first time I picked my truck up 4 times never leaving the dealer. Now I have been taking it to another dealership and they seem to have a better diesel mechanic. I've had my truck for a week or so and now I think that i have another bad injector. So will EFILive diagnose a bad injector or high flow rate? And can I turn injectors off one at a time? The reason being, my truck is knocking and I'd like to find out if it's an injector or not. So far I've relied on my ears and I'm starting to dought myself. thanks
