P0171 lean code, but long term fuel trim 2.3??
Have a p0171 code indicating I have a lean condition. To my surprise, my Long Term Fuel Trim is 2.3 and is normal.
Anyone have any ideas on how to zero in on the problem? How could I get a lean code with a normal Long Term Fuel Trim?
I have an erratic idle at start up in the morning.. Is this another case of the infamous $12 hose??
