Catalytic converters are component of a machine's exhaust action that chop the magnitude of nitrous oxide produced by burning fuel. When working properly the converter should not move fuel economy, however it can provided it becomes clogged or damaged.
Exhaust Backpressure
Provided your machine's catalytic converter becomes plugged or clogged, it restricts the airflow of exhaust from the engine. This causes increasingly exhaust to accumulate in the engine which reduces the proportions of late, combustible oxygen the engine pulls in. A common cause of a clogged catalytic converter is overheating due to a misfiring spark plug.
Diagnosis
Solution
If your catalytic converter is clogged or damaged, it will need to be replaced. Make sure to enquire the reason that the first converter was ruined so the replacement does not suffer the same fate.When it is receiving less oxygen, the engine must work harder to accomplish speed. This increased work lowers fuel economy, reduces power when driving at high speeds and can cause overheating and stalling. If your car runs normally for a few minutes after starting, but then begins to cough or sputter, your converter may be clogged. Especially if you have noticed other symptoms, have your mechanic check the car's exhaust backpressure.
