Message	thru disconnecting ignition coils, i have narrowed a miss down to rear most passenger side cylinder. suspect it is the injector since switching one coil pack from a good firing cylinder didnt change anything when put on that back problematic cylinder its a 90 turbo Z that has been sitting for too long (new projects took over, started fixing house up) was running okay when put away. fuel is old I have cleaned up the terminals with a small wire brush and di-electric grease to no avail. I am contemplating pulling injectors (stock 370) and replacing with new bigger 550cc so that I could run a little more boost possibly. The ecu was a jwt stage three. Would this need to be reprogrammed for bigger injectors? Also contemplating driving the thing as is to see if it clears up... could the injector be sticking? What do you guys think?
