stopped by a gmc dealer just to ask if they could check to see if my injectors was inline (just wonderin)and working ok (i told them i had seen some white smoke a few times also) and they said that they couldnt check and tell anything about them with a tech 2 unless the service light was on because it dont tell ya nothing like that. is this true? i know i have seen some talking about them being in sink or something before......he did say in the year he has worked there he has only has 3 trucks in for injectors and this is a huge dealership also.

I don't think that is true but you might PM SP33D. He has one and I saw him looking at IBDMAXN's injectors during the dyno . . . .

They could check your balance rates for you with a Tech II. If you have a predator you can check your own.
