The computer system in your vehicle needs to be checked for possible problems. Most cars have very sophisticated systems and one problem can set off a chain reaction that makes finding the problem very difficult. The engine will be hard to start and may die or idle rough. Another maintenance item is cleaning the intake manifold, valves, fuel system, and fuel injectors. It will improve performance, fuel economy, and driveability of your automobile.
Every car comes with an owner s manual and it gives general time guidelines.
Also, a car needs more maintenance when weather conditions are extreme. A tough winter can play havoc on an engine. Expect to have more problems and catch them before you run into real trouble. Until next month. Happy Holidays and safe motoring.
