Abstract

The P0302 error code indicates that your Acura's engine management system has detected a misfire in cylinder 2. This means the air-fuel mixture in the second cylinder is not igniting properly, which can cause rough idling, reduced power, poor fuel economy, and potential engine damage if left unaddressed.
