Description of Engine Diagnostics and Performance
Every vehicle built since 1996 has been equipped with an On-Board Diagnostics System that monitors engine performance. Discrepancies in performance levels are reported through your vehicle’s computer system. Once the “check engine” or “service engine” light is displayed, your next step should be to seek out an engine diagnostic service or an engine tune-up. Engine diagnostics allow our staff to gather helpful information about the operating condition of your engine. The insights obtained during an engine diagnostic will determine the extent of suggested engine repairs. The most common diagnostic trouble codes are generated in response to malfunctions in the powertrain. Ultimately, regular engine tune-ups are necessary to optimize engine performance. A tune-up is also one of the most effective ways to prevent unexpected engine trouble. During an engine tune-up, our staff may replace the spark plugs, spark plug wires, air filter, fuel filter, and distributor cap and rotor in your vehicle. Our experts will also check emission levels, fuel lines, and belts and hoses. Engine diagnostics and regular engine tune-ups can help extend the life of your vehicle and improve the health of your engine.
Benefits of Engine Diagnostics and Performance
While regular engine maintenance will help ensure that your engine always performs at peak conditions, there are also signs you can look for that indicate an engine repair service is needed. The “check engine” or “service engine” light is a sure sign that your engine should be looked at by an expert sooner than later. Most of the time, your vehicle’s On-Board Diagnostics System will detect an engine issue and store the corresponding repair code, which can be accessed by a member of our service staff. Slow-cranking, rough idling, stalling, knocking, or pinging while accelerating are all signs that you should seek engine repairs or engine diagnostics to determine the full extent of your engine trouble. A decrease in gas mileage and detectable loss of power during acceleration are also signs of an impending engine tune-up or engine repair service. Engine warning lights help alert drivers to minor issues before they become major repairs. Be sure to follow up with our staff once your vehicle's On-Board Diagnostics System detects a problem with your engine.

How do I know when my car needs a tune-up?
You should bring your car in for a tune-up if you notice any abnormal sounds or odors, a lack of efficiency, or general rough riding. The most common signs include the check engine light coming on, stalling engine, vibrations throughout the vehicle, pulling, or worsening fuel mileage.

Preventive maintenance and car tune-ups help reduce the chance of your vehicle unexpectedly breaking down. We recommend regular oil changes, spark plug checks, fluid checks, belt and hose inspections, alignments, tire rotations, and consistent brake and light checks.

Your owner’s manual provides all necessary information regarding what parts to replace and when to do it. Read it thoroughly and note any exceptions or severe service notations.

Customer Testimonials
We stand by our work.
The owner John is very knowledgeable and the whole staff is friendly. I came for an oil change and to have my tires serviced (rotation, alignment and balance) because I thought they needed it. John told me I didn’t need service to my tires and they rode very well; no need to spend the money on a service that wasn’t needed. We all know many establishments would try to push a service for a dollar so his honesty is appreciated. Reasonable pricing and great service. Highly recommend! Services: Tire rotations, Oil change

Very knowledgeable HONEST people. Saved me over 2K based on a quote I would have received from another shop. Services: Tires, Steering & suspension repair, Brakes, Electrical
Ronnell FieldsGoogle ReviewI had slow leak from a nail puncture and I was told by another tire shop that run flat tires could not be fully patched. He said it would cost $75 for a temporary fix but he recommended replacing, so I bought another tire online. [...] Thomas did such great work that it was not a temp fix at all and basically let me know the other place did not know what they were talking about. I have had no issues with the tire and its been over 3 months. He also said the repair came with a lifetime warranty so this place is all good in my book. Highly recommend. Service: Tires
