I'm trying to track down a strange issue with my expy. It runs RICH. However, there are no codes at all being produced. I replaced all 8 injectors about 3ish years ago with the updated part numbers that fixed the leaky/stuck ones from the factory. So I'm relatively sure it's not that. I'm just not sure why it would be running so rich. It seems like at idle/slow speed round town stuff it's worse than if I can get some expressway/highway driving. Sometimes there's a hint of rough idle, but its slight and not all the time. What values in FORSCAN should I be looking for to give me some hints? I don't think my little bluetooth OBDII with TORQUE Pro is going to give me the insight I need. Could I have some bad plugs and they're working enough to not trigger misfire?
