Sluggish O2 sensors don't just trigger annoying Check Engine Lights; they cause poor fuel economy, rough idling, and can even degrade your expensive catalytic converters over time.
Over time, factory oxygen sensors degrade from extreme exhaust heat and carbon buildup, leading to poor fuel economy, lost performance, and failed emissions tests.
