Have a 2018 cheetah with a Kohler 29 efi and I'm pretty sure the oxygen sensor is bad. It spits and sputtering with black smoke out the exhaust.
Unplug O2 sensor and it runs perfect. It had a Delphi OSP+ 28163974 on it. Any Napa or auto store chain that has a replacement? I called Napa and they said no matchup. But reading old threads on lawnsite members were saying there is.
Anyone know?
