J & E Automotive Repair at 7501 University Avenue in La Mesa operates a general mechanical service bay covering oil changes, brake jobs, engine diagnostics, and scheduled maintenance for foreign and domestic vehicles. Collision-damaged vehicles requiring body or structural work before mechanical service transfer to corridor collision centers such as Fix Auto La Mesa, which handles insurance-grade panel, frame, and paint restoration on the El Cajon Boulevard stretch. The shop covers cooling-system flushes, serpentine-belt replacement, alternator and starter swaps, suspension components, and check-engine-light diagnostics along the University Avenue commercial strip. Customers needing a vehicle during multi-day engine or transmission work arrange rentals through La Mesa agencies such as Enterprise Rent-A-Car, which maintains a local branch for same-day pickup. The facility specializes in OBD-II live-data stream analysis, fuel-system pressure testing, and ignition-coil diagnostics to isolate intermittent misfires and hard-start conditions on high-mileage import sedans.
