Apparrently, the closed loop mode does not function correctly.

hello Minnet,
on my car there is no Oxygen sensor , because there is no catalysator (as far as I know)
could you tell me how it works in this case?
EHA, OVP, coil, and lot more have been replaced and car is still erratically stalling.
thanks
