My dad would tune cars by ear and diagnose troubles by experience. With todays automotive advancements diagnosing issues requires a much different approach. We still listen but it's to our customer. We use our advanced diagnostic equipment to check the function of injectors, coil packs and sensors.
An illuminated check engine light may be the sign of a costly repair or a lose gas cap. We use our scanner to pull the codes and then interpret them. A&J Garage will have your gas or diesel engine running like a top!
