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.
The commonest cause for electrical faults in cars is the 'short circuit' which typically is caused by the so-called 'clashes' in the wiring system. Unless you are professionally qualified in the field of auto vehicle wiring (or mechantronics), you are advised against attempting to carry out auto electrical repairs on faults emanating from 'short circuits.' Getting things wrong here could, in the worst case scenario, see your car up in fire!
