San Diego Auto Repairs at 1502 Broadway in Chula Vista provides general mechanical service, muffler and exhaust work, oil changes, TPMS resets, and check-engine-light diagnostics for cars, trucks, and SUVs. The shop sources hard-to-find exhaust flanges, catalytic-converter cores, and discontinued muffler assemblies through the salvage network that includes Import Auto Wrecking, keeping repair costs down on older vehicles that lack current aftermarket support. Exhaust service covers catalytic-converter diagnosis, muffler replacement, and flex-pipe welding on both domestic V-8 platforms and four-cylinder imports along the Broadway corridor near Costco and Walmart. Brake service, A/C recharging, and tune-up work round out a menu that keeps the 1502 Broadway bays running parallel repair streams, and customers whose vehicles require multi-day engine or transmission work arrange interim transport through Men In Black Transportation in Chula Vista. The most involved service procedures include catalytic-converter efficiency testing via upstream and downstream O2-sensor waveform analysis on a four-gas exhaust analyzer calibrated to BAR-97 specifications.
