I would like to know more about the injector cleaning. where exactly to connect that little machine the run rite .
to what hoses exactly please. This car did not have any codes and it was leaking a lot of fuel by the injector rail. I got another injector rail with some other injectors and now is not leaking fuel anymore but it has a lot of codes, it has P0171 system tand o lean fuel trim, system to lean A/F lean bank 1, P0300 Random/ multiple misfire, P0301 cylinder 1 misfire, P0304 cylinder 4 misfire. This car has new coil on plugs and good sparkplugs, it all started when I changed the fuel rail with the other injectors. The injectors that I got are used but they look better that the original ones, I just think that are clogged and that is why it came out the misfires, what do you ALL THINK, I NEED HELP SCOTTY, PLEASE
THANK YOU ALL.
never put in used injectors. At least make sure the o-rings are good. Also listen for vacuum leaks.
You could be right about the injectors being clogged. Clean them then try again, If it doesn’t work, no harm done. Just get new ones. Also the reason you got no codes before is because your injectors still injected the appropriate amount of fuel even tho the fuel rail leaked
