Auto Tune Up in Walnut Creek, CA

Diablo Auto Specialists is a family owned auto repair garage in Walnut Creek. We provide comprehensive auto care, including tune-up service.

The concept of a tune-up has evolved over time. Older cars required a lot of technician’s time to truly tune the car. Modern vehicles are full of embedded computer and sensors that send them information, as a result, in large measure newer cars are “self-tuning” – computers adjust parameters for in real time to keep the care performing optimally.

Minor tune up in the past involved inspections of hoses, belts, wires, check for vacuum leaks, coolant leaks, oil leaks. It might also include ignition timing adjustment and/or spark plugs replacement.

A major tune-up added transmission fluid replacement, often fuel pump replacement, and replacement of various sensors and a check of the systems interacting with these sensors.

By comparisons, modern vehicles do a lot of “tuning” in real time. The on-board computers read inputs from dozens of sensors, and based on that information can adjust things in real time, like how much air goes into the air-fuel mixture, and based on that, can calculate emissions. Computers will try to correct problems as they spot them, but if they cannot, that’s when the check engine light comes on.

Fortunately, the check engine light often gives a warning in the early stages of the problem, thus mechanics can often correct things before they lead to damage or expensive repairs. With all the computers looking over your car, modern tune up still involves expert mechanics looking for leaks, checking belts, hoses, and replacing spark plugs, water pump or fuel pump, as needed. Computers can warn us about possible problems, but it still takes a human to find the root cause of a problem and to get it corrected.
