Computerized Engine Analysis

Your modern vehicle's engine is a highly sophisticated piece of equipment. Our factory-trained technicians are here to make sure your engine is in peak operating condition.

The days of your father's gas-guzzler are long gone—instead, Federal Exhaust Emission and Fuel Economy regulations demand that today's vehicles be equipped with electronic engine control systems, to curb carbon emissions and increase fuel efficiency. With technically-advanced control systems taking the place of simple engine components, common maintenance services such as tune-ups are also a thing of the past. Regular services (such as spark plug and filter replacements) are still required, as well as a computerized analysis of your vehicle's control computer.

This dirty air passes through the mass airflow sensor, and starts to accumulate on the delicate sensor element. The mass air flow sensor measures how much air is getting into your engine.
