Getting the "Injector 3 Low Voltage" when pulling codes. Car is running very rough, won't idle, sounds like it's on 3 cylinders, and then eventually throws the P1507 IACV error which I think is just a symptom of the injector issue.
Issue doesn't follow the injector, swapped it with cylinder #2 and the issue and code is identical. Injector was nice and clean.
What are the recommended ways of testing this? Should I see a certain resistance from pins 1-2 on the injector itself, what sort of a resistance / voltage should I see on the injector wires?
Would misplaced vacuum lines on the intake side have anything to do with the car only running on 3?
Thanks!
