In practice, you should not operate a road vehicle …
Do any cars have air-cooled engines? Yes—but only in very limited contexts today. No mainstream automaker sells a new, mass-produced air-cooled car. Air-cooled engines survive mainly in classic vehicles still on the road, low-volume replicas or kit cars that reuse old designs, and a handful of recent three-wheelers (now discontinued) that used motorcycle-style engines. For …
What happens if I unplug my upstream O2 sensor? If you unplug your upstream oxygen (O2) sensor, the engine control unit (ECU) will switch to open-loop fueling, turn on the check engine light, set fault codes, likely run the engine richer, reduce fuel economy and performance, increase emissions, and risk damaging the catalytic converter—so it’s …
