The Professional DifferenceApril 22nd 2022

The old-fashioned tune-up used to be done “by ear”, but this isn’t possible with computer-controlled engines. A complete diagnostic check, followed by professional service, should be performed at factory-recommended intervals, or whenever your car shows any of the above warning signs. Our expert technicians can:

Tap in and read the signals being sent between the computer, its sensors, and the output devices

Restore your car to original performance specifications, reliability and emission control requirements
