With advances in engine electronics and spark plug technology most new cars (1995 and up) don’t require tune-ups. For older cars, regular tune-ups are still essential.
An engine which misfires (runs rough) can cause premature failure of the catalytic converter and ignition module.
During our tune-ups we check engine compression; ignition wire condition; clean the carburetor or throttle plate; replace the fuel filter and check and adjust the ignition timing and idle speed.
Even if your car has an extended tune-up interval (96,000 km or more) fuel filters still need replacement every 48,000 km or 30 months.
Recommended Frequency: Intervals vary but most common are 48,000 km/30 months or 96,000 km/60 months
