Little troubles, such as a misfiring stimulate plug, a defective sensing unit, or an ineffective gas injector, can progressively get worse if left unattended. With very early detection via engine diagnostics, auto mechanics can deal with these small issues prior to they cause considerable damage.


For example, if a sensing unit detects that the engine is running rich or as well lean (inadequate or excessive gas), this can bring about enhanced wear on engine parts or bad fuel performance. By detecting this early, the mechanic can readjust the air-fuel combination, avoiding expensive repairs later.
