Is your Acura TL 2005 engine giving you trouble? Common issues include oil leaks, timing belt wear, and rough idling caused by faulty sensors. Start by checking the P0420 catalytic converter code and inspecting the PGM-FI relay. Regular coolant flushes and fresh spark plugs can restore lost power. Replacing the valve seals early prevents costly internal damage. With proper maintenance and OEM-grade parts, your J32A3 engine can reliably run well past 200,000 miles.
