My 96 primera just failed its mot on it emissions,lambda reading too high.What is the lambda reading?how can i lower it?By the way the car doesnt idle very well when its warm,low erratic revs and cuts out,anybody have any ideas?
My car failed MOT last week on the same thing.
All these was fine aprt from that same point on the emissions test.So i was told to buy a universal sensor of these guys and now car runs like new,and passed retest no problem.
