injectors 3 and 5 randomly fire or stay open they sometimes fire over 30 times a sec at idle ,completely random
there seems to be nothing wrong with the ground wire (white with red stripe) for the two injectors, could it be a possible ecu problem? ecu has been recapped about a year ago and doesn't show any type of damage
also they fire without the engine running just with the key on, it makes no sense to me, im rewiring the entire harness right now

this problem came out of nowhere then was gone for two weeks and the car ran without issues then i filled up and it started again

im going to etown this sat and would really like to get this resolved, anyone have a similar issue?
