System is running lean and strong fuel smell P0174 - System running lean
This code recently popped up and I haven't been able to figure out what is going on. Recently, I have been able to smell fuel very strongly when idling ONLY if the A/C is on. I can also smell fuel in the engine bay. I have noticed that cylinder 5 seems to have some moisture near the exhaust port.
I imagine that the system is "running lean" because the gas it is using is not making it into the motor. There is clearly a leak somewhere and I do not know how to properly check.
