Common Causes of a Check Engine Light Warning in Boise

check engine light boiseYour vehicle’s check engine warning can be either helpful or infuriating. Since the light can be triggered by many things, it’s important to narrow down the possibilities. Knowing some common causes of a check engine light warning can help. 

Loose Gas Cap

One common and incredibly easy-to-fix reason for your check engine warning to come on is a loose gas cap. It can be easy to forget to screw it all the way on when refueling. This can cause a vacuum leak that may trigger the light to come on. 

Worn Spark Plugs

Your vehicle’s spark plugs need to be replaced every 80,000 to 100,000 miles. If they’re worn out, you may experience a misfire, which can turn on the check engine warning. New plugs can turn off the light and give you better performance. 

Bad Catalytic Converter

Your catalytic converter is incredibly important and over time, will eventually wear out. When this happens, you may notice a sulfur-like smell coming from the exhaust. It will also most likely turn on your vehicle’s check engine light
