System Too Lean (Bank 1) Basically this means that an oxygen sensor in bank 1 detected a lean condition (too much oxygen in the exhaust). You will more than likely not notice any drivability problems, although there may be symptoms such as a lack of power, detonation (spark knock), and/or a hesitation/surge on acceleration. A code P0171 may mean that one or more of the following has happened: The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry. There could be a vacuum leak downstream of the MAF sensor. In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling Inspect all vacuum and PCV hoses, replace if necessary Check for a dirty fuel filter and proper fuel pressure.

Why did they stop making the Chevy s10?
They didnt stop making the S-10. It was repackaged and sold as the Chevy Colorado in 2004 This answer is incorrect as the Colorado was not a repackaged S10 but was instead and entirely new vehicle. It was sold right along side the new and entirely different Chevy Colorado that first year. The last year the Chevy S10 was made was 2004.
