A code is a starting point, not an answer. "P0171 — system too lean" can mean a vacuum leak, a dirty sensor or a weak fuel pump. We test until we know which.
What is included
- Full code scan of every module
- Pinpoint test of the suspected part
- A written report with photos
- The fee comes off the repair if you go ahead
Signs you need it
