i did a buzz test and it kicked out a dtc for injector 3 high to low side fault. so i unplugged that injector and ran the buzz test again. to my surprise i heard a faint buzz when injector 3 was to fire. then i unplugged the whole harness on passenger side and ran the test again. when it was injector 1, 3, 5 and 7's turn to fire i heard a faint buzz from drivers side bank. is this normal? i have also ohmed out each injector wire at idm and they all came in around 3.1 ohms. this leads me to believe the wiring is intact. possible pcm malfunction?

Did you ever figure this out? looks like I may never get my answer to this faint buzz question if you haven't had a reply in almost 2 years
