Engine Diagnostics in Philadelphia

Every vehicle manufactured since 1996 comes with an On-Board Diagnostics System. This system monitors the vehicle's engine performance and reports any discrepancies through the vehicle’s computer system. When the check engine light comes on, it is a signal that you should seek out an engine diagnostic service or an engine tune-up.

When your check engine light comes on, call any of our locations and we will be glad to give you peace of mind and identify what is causing your engine trouble.

Engine Diagnostics and Tune-Up Process

Engine diagnostics are a method used by our staff to gather information about the health and operating condition of your engine. This information is vital to determine the extent of any necessary engine repairs. The most common diagnostic trouble codes relate to malfunctions in the powertrain. Regular engine tune-ups are a proactive way to optimize engine performance and prevent unexpected engine troubles. During a tune-up, our team may replace various components such as the spark plugs, air filter, fuel filter, and distributor cap and rotor.

Warning Signs for Engine Repairs

There are several warning signs that indicate the need for engine repairs or diagnostics. These include slow-cranking, rough idling, stalling, knocking, or pinging while accelerating. A decrease in gas mileage and a noticeable loss of power during acceleration also suggest the need for an engine tune-up or repair service. Engine warning lights are designed to alert drivers to minor issues before they become major repairs.
