have just had the oxygen sensor replaced, the vehicle performs flawlessly so long as the check light is OFF. Of late the light comes on within minutes of starting the engine, the nett result is a momentary loss of power at takoff (engine almost dies then picks up) this condition can be avoided by VERY,VERY gentle accelerator pressure, but it is not really practical to offer such gentle accelerator pressure to avoid the problem. Where do start looking for this problem?
