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!
What are the signs and symptoms that might make you think your vehicle needs a tune-up? A misfiring engine (when spark plugs ignite at the wrong time) could be caused by worn or fouled spark plugs. Bad spark plugs can also cause low fuel economy, hard starting and sluggish acceleration. Most plugs, though, should last 100,000 miles or more, and engine computers do a remarkable job of compensating for worn plugs, so that might not be the main or only culprit.
