Re: 2000 Jimmy error codes?
Not sure about bank one, Scott, but running rich is 'cuz SOME sensor is sending to the computer a [faulty] signal saying 'cold motor', send extra fuel.
Does your temp guage reflect a warmed up motor after 5 - 10 minutes? There are other sensors which pick up on engine temp, and then do their thing, but for those sensors, there is more than just a temp guage (some don't do their thing UNTIL the computer gets a 'engine warmed-up' signal from the temp sensor.
