I have a vx 5.7L it has a crook Oxygen sensor its not completly ####ed but its getting there, The new one wont come till next week How bad is it to still drive it while its playing up i know bad fuel eco bad performance. But will it do any damage to the motor to drive while the new one comes??
Won't do any damage what so ever. The only thing you will notice is the engine light on. Probably won't notice any change in performance or economy.
I drove round with engine light on for two weeks before I got round to changing mine no problems at all
