When doing auto electrical repair, the first vehicle component your should acquire knowledge about is the car battery. Even though the battery only store 12 volts, it is the electrical source of the entire vehicle. You will not be able to start your engine without the battery. In addition the auto battery helps to operate all the electrical accessories installed on your motorcar. An auto battery should last 3-5 years in average climates. Extreme hot or cold climates however, will reduce this to only 2-3 years.
Engine deposits caused by low-quality or contaminated gasoline create drivability problems, and the cure for that might be a fuel system cleaning, either by a repair shop or with a gas-tank additive. An illuminated check engine light signals when something is amiss in the emissions control system, but depending on what the issue is it could also affect fuel economy or engine performance, so don’t ignore it. A faulty oxygen sensor, for example, leaves the engine computer in the dark about how to set the air-fuel mixture, and that can result in poor fuel economy.
