All of the wires on the harness are the same. How do you know which plug goes to which injector? Also, on my fuel pressure guage, I get a reading from 39-44 psi in very quick succesion. All I can see is a blur basically. Originally I had a massive vacuum leak that I fixed and it would stay steady but it is doing it again. Besides another leak, what could cause this. I know it is killing performance and effeciency. Please help me. Thanks

 

Your injectors are bank fired. It matters little which is which. All the left ones fire at the same time so plug away.

What else could cause a flutter like that? Pad FPR

 

Whats the point of bank firing? It sounds sloppy and wasteful because there are a bunch firing and not getting ignited. Or maybe I just dont really understand the process. Could someone enlighten me? Thanks
