The Basic Engine Analysis includes A visual check of the components under the hood, Electronic check of ignition system,timing controls and cylinder efficiency, gas analysis of the emissions and a computer check for trouble codes. This in-depth procedure determines the problem areas. A complete written quote is prepared and reviewed with the customer and only authorized service and repairs are performed with top quality parts.
