I think its a lost cause Empire, I've had my 300 for 5 years now and I love Nissan, I guess he took it the wrong way, anyway, I ohm tested all of my injectors today and im kind of confused...I got between 12.8-14 ohm readings on 5 of my injectors (I had to re-clean one of them which is no longer not firing) so im back to 5 cylinders, the puzzling thing is on the last cylinder I got no reading what so ever, I cleaned it for about 15min it looks like brand new contacts no green corrosion but still no reading, im guessing that means its just 100% dead? And for everyone having this similar problem my suggestion would be take your time and clean each injector as best as you can as well as the plug, and buy some contact cleaner, helped one of my cylinders...
