99 E-150 4.2 Bank 1 Too Lean
The reading came from local parts store,suggestions were one of the o2 sensors,bad gas, acually runing lean. My question is how many sensors dealing with this symptom are related ? I understand that bank 1 is located on the #1 cylinder side of the engine.Could it also be a sensor located on the exhaust piping ? Any ideas would be greatly appreciated.Trauck seems to run fine. thanks in advance.
