What are the Symptoms of a Clogged Exhaust Filter?

There are a few symptoms that can indicate that your exhaust filter is clogged. These include:

  • Loss of power: A clogged exhaust filter can restrict airflow to the engine, which can lead to a loss of power.
  • Increased fuel consumption: A clogged exhaust filter can also increase fuel consumption. This is because the engine has to work harder to push exhaust gases through the filter.
  • Rough idling: A clogged exhaust filter can also cause the engine to idle rough. This is because the engine is not able to properly combust all of the fuel.
  • Check engine light: A clogged exhaust filter can also trigger the check engine light. This is because the engine’s computer detects a problem with the exhaust system.

If you notice any of these symptoms, it is important to have your exhaust filter inspected by a qualified mechanic. A clogged exhaust filter can damage your engine, so it is important to have it repaired as soon as possible.
