Don't Ignore the Check Engine Light ! Don't procrastinate, could be Costly if you do!
Motorists who ignore the check engine light get less miles per gallon and could face costly repairs down the road.
Many people fear that when the check engine light comes on, it is going to mean several hundred or more dollars in repairs, so they ignore the light and hope the problem goes away. By not addressing the cause of an illuminated check engine light can cost you in terms of wasted fuel and more expensive repairs in the future.
When the check engine light is illuminated, it usually means that the vehicle system, such as the ignition, fuel injection or emission control, is not operating properly, even if the vehicle appears to be running normally. Most common reasons:
Replace O2 sensor(s)
Replace ignition coil(s) and spark plug(s)
Replace catalytic converter
Inspect fuel cap and tighten or replace as necessary
Replace evaporative emissions (EVAP) purge control valve
