Our factory-trained technicians prioritize quick diagnostics: we perform a complete OBD-II scan, battery and charging system tests, and targeted inspections to prevent further damage. In many cases a weak battery or failing alternator can cause voltage irregularities that trigger intermittent misfires or electronic faults; diagnosing and replacing a battery or alternator with OEM parts restores stable voltage and prevents repeated codes. We explain each recommended repair, show parts and labor breakdowns, and highlight how doing the job correctly saves you money over time by avoiding repeat visits and costly catalytic converter replacement.
