P0170 - P0171 codes on 1997 Prelude

Question

I have a check engine light on and the codes are P0170 and P0171

Answer 1

HI there

These codes mean there is a fuel mixture problem and a lean fuel mixture on bank 1. Most of the time this is the result of a bad front O2 sensor or a possible intake manifold gasket leak causing the lean fuel mixture.
