    LB7 injector balance test

    I just picked up an old Silverado with a LB7. I haven't even connected my HPT cable to it yet. I've owned it for 16 miles, and now I have a P0093.

    How much can the HPT scanner do? Can it perform an injector balance test? How about changing the commanded fuel rail pressure?

    I suppose if it can't do these things, I'll have to borrow a friend's Tech 2.
