Title: P0171 Engine code
Post by: antonix27 on May 10, 2025, 08:40:01 pm

Hello,

Driving down the road the other day and got a check engine light. Engine was still running fine, when I plugged in OBD comp, it chucked p0171 system too lean bank 1 code.

Fairly new to car troubleshooting and wondering if anyone has any ideas on how to pinpoint exact issue/fix.

Thanks
