It means your car is running lean...not just the #1 cylinder. Inspect your fuel injectors.

P0171 is the OBD II code for bank one lean. Since your Neon only has 1 bank, it means your entire engine is running lean. Low fuel pressure, clogged fuel injectors, vacuum leaks or MAP/MAF reading incorrectly are the usual suspects.
