Rochester Multec
Coil windings short out internally resulting in a drop (or rise) in resistance. These can sometimes be tricky to detect at home. When the injector is not being pulsed, the injector could ohm out to spec, but once they are energized the problem shows its effects and the resistance will rise or fall. Once this problem occurs, there is nothing that can be done other than to replace the injector.
These were commonly found on many GM models from the late 80's to early 90's having a grey or black top.

ok guys, this was not an easy one to find and has caused me weeks of grief.... fault only occurred once the coil was energised a few times... real biarch to find when there is fuel going everywhere... i have spare standard injectors to help fault find this process... it feels like a coil pack has gone... but it aint!!!!

been having trouble wouldn`t rev past 6200 went through everything after hearing retro`s injector probs thought maybe chuck standard injectors back in hit 8000 before i could get off the gas rode around a bit keeping revs to 7500 didn`t want to cook anything with 14psi and little injectors swapped injectors back over revved past 8200 then straight back down to 6200 moral of the story when upgrading to gain performance don`t buy cheap crap ie the $200 injectors on greenhulk
these injectors have only run for 35hrs last 5 hrs chasing my tail to find out whats wrong

i`de be careful with that hug now that i`m a single again retro
