How do I change the O2 sensor 1 in bank 1 in a 1999 Daewoo Lanos?

iirc sensor 1 bank1 is a pre cat lambda sendor. Its the first one visiable on the manifold/downpipe from the engine before the catalytic converter. you just undo the multiplug and remove the sensor with a spanner turning the whole sensor anticlockwise, screw in the new sensor, tighten it up and reattach multiplug.

You have 4 oxygen sensors, (bank 1 sensor 1, bank 1 sensor 2, bank 2 sensor 1 and bank 2 sensor2). Follow the exhaust from the head of bank 1. The first sensor you come to is sensor 1, the second is sensor 2.

How do you fix a code p0171 system to lean bank 1 on a Daewoo Lanos 1999?

Check the tubing going from the air filter to the intake manifold to see if it has come loose. This might account for extra air going into the intake manifold than the computer is aware of. Otherwise it may be due to a faulty(or dirty) MAP/MAF sensor. Another possible cause is from low fuel pressure due to restricted fuel lines or a bad fuel pump.
