recently purchased a link g4 plugin for s13/180sx ca18det. Car runs sweet on stock ecu, installed link g4 and it doesnt fire on 4th cylindar. Injector seems to be firing, has spark and cconpression. Has power and pulse at injector so its definitley firing Other 3 cylindars seem to be sweet, just wont fire on 4th. Is there a drama with trigger setup perhaps? Appeiciate any help
