Engine diagnostics becomes necessary the moment your check engine light or any other warning light appears on your dashboard, or if you notice a drop in performance, increased fuel consumption, rough idling, misfiring, or unusual smells from the engine bay. While some warning lights indicate minor issues, others can point to more serious problems that worsen if left unchecked. Customers across West Mesa, Nob Hill, Corrales, Placitas, and Lomas Boulevard bring their vehicles to P Garages and Mechanics knowing they'll get an honest, accurate diagnosis without being pushed into unnecessary repairs.
