What to Do When the Roadside Emission Test Shows Exceeding Limits?

[TravisRose]

If caught with excessive emissions, you will be subject to corresponding fines and a deduction of 3 points. Below are the reasons for excessive emissions: 1. Use of inferior fuel: Using low-quality fuel can lead to incomplete combustion in the engine, resulting in carbon deposits. When we notice an unusually strong smell from the exhaust, we should go to a certified repair shop for inspection and timely resolution. 2. Clogged catalytic converter: A clogged catalytic converter and malfunctioning oxygen sensor are also causes of excessive emissions. We should first check the OBD system, then flush the catalytic converter, clean the fuel injectors, clean the throttle body, intake manifold, etc., and add a lubrication system repair and protection agent.
