Reasons for failure are often related to some of the simplest maintenance tasks, such as:
Dirty oil and oil filter: Making sure you have clean oil isn’t just good for engine performance—it also means cleaner emissions. A regular oil and filter change is one of the least expensive but most important things you can do to prolong your vehicle’s life.
A dirty air filter: Your vehicle may emit high levels of hydrocarbons when your air filter is clogged and no longer effective.
A lit “check engine light”: Regardless of the cause, if your “check engine light” or “service engine soon” light is on, your vehicle won’t pass the emissions test. Any time this light comes on, you should promptly bring your vehicle to Lamb’s Tire & Automotive. We can determine why the light is on and address the underlying issue.
A gas cap problem: This is a common reason vehicles fail the test, and the solution may be as simple as tightening the cap. It could also be a cap that leaks, in which case you will need a new gas cap.
Bad spark plugs: Spark plugs play an essential role in creating the combustion that powers your engine. When the combustion process isn’t functioning properly, your vehicle may fail the emissions test.
