Not that I know of but I'm not gonna say that it hasn't. What I don't get is. I straight wired the ecu to the ptu and the ptu to the coil and use a separate constant and ground for the coil connector. But the same plug still stopped firing when I wiggled the harness. And the injector was still working as it should. Unless there is another wire that I have to run that I am unaware of. At this point I'm sick of digging through the harness I just wanna wire what I have to and be done with it lol.
