Check Engine:Lean Condition
My mom's 3rd gen 4runner has the check engine light. The code is "Lean condition". Dad asked the guy if thats what comes up for a bad o2 sensor or tps and the guy says no those are specific codes. Same with an injctor not firing.... Any ideas?

Thanks,
Kelly

Was it Code PO171? If so, try cleaning the MAss Air Flow Sensor (MAF) and she should be good to go. Try a search for this exact topic.
