While the process of car and truck tune-ups has changed through the years, its importance has not.
Tune-ups are a critical part of auto maintenance, ensuring one's engine is working properly and efficiently. AAA Auto Club, www.aaa.com, advises one to take one's car to a service technical for an engine inspection and computer scan every 30,000 miles, though it is best to check your owner's manual for more specific mileage recommendations. !Engine Inspection
An engine inspection involves a technician checking all your engine functions by hooking it up to a diagnostic analyzer. A diagnostic analyzer will ensure that there are no problems in the ignition, fuel and emissions systems, and will allow a technician to return your engine to its factory specifications. This may require replacing faulty spark plugs or ignition wires. AAA recommends replacing these components in sets rather than merely replacing those which are in poor condition.
A computer scan is one a car's computer is scanned to reveal electronic sensor and exhaust system wear. A technician can spot faulty sensors and other mis-adjustments which can affect gas mileage, cause running or idling problems, and increase emissions. Not all cars with on-board computer are capable of being 'scanned,' particularly older models.
