Have any you guys ever had a faulty EFI relay? Yesterday my ecu started throwing code 16 which is for the injectors and was being kind of hesitant depending on throttle pressure. So I got home and one at a time unplugged an injector to see if they were working properly, each one that unplugged made the motor idle down due to the lack of fuel to the cylinder, which means they are okay, so now I am stumped, could it be the EFI relay? I converted the car to MPFI but that was like almost 4 years ago so I know every thing is wired correctly, and I am running a PM6.... any ideas?
