San Diego Auto Clinic in Point Loma operates the full-service mechanical repair bay at 3546 Barnett Avenue in the Midway District, sharing the same facility that houses the STAR-certified smog operation next door. Brake repair, timing-belt replacement, pre-purchase inspections, engine and check engine light diagnostics, transmission service, and electrical troubleshooting run through the repair side, with vehicles that need post-repair emissions verification walking across the lot to the test lane at Point Loma Smog on Rosecrans. The Barnett Avenue location sits between the Pechanga Arena corridor and the Nimitz Boulevard gateway to the 92106 peninsula, pulling maintenance traffic from both the Midway District and the residential Point Loma hillside. Catalytic-converter diagnosis and replacement are among the most frequent repair-to-retest workflows, with OBD-II code verification confirming the repair before the vehicle returns for its smog certificate. Brake and suspension work feeds into alignment checks coordinated with tire-service operations such as Firestone Complete Auto Care on the Rosecrans corridor. The most complex single ticket is a full engine-management diagnosis tracing an intermittent misfire through coil packs, fuel injectors, and PCM calibration to clear a persistent P0300 random-misfire code.
