My car was giving me the classic 30bb code and I assumed it to be bad mosfets. Tested them all and it seemed to be fine. Find out a loose ground shorted out Injector 5. I get new injector and coil pack coded and everything but the problem remains. Weird thing is when I disconnect injector 5 all together the car gets rid of the 30bb and it runs on all the other cylinders but obviously not 5 because its not plugged in. Could this be because the wire going to injector 5 is bad? If so how would I go about testing that to find out. Im going to be replacing the mosfets anyways since i already have the new ones.
