Had MOT a few days ago and noticed on the emissions sheet, it quotes the Lambda as being 1.02 (whatever that means) lmao
Anyways, it says the minimum should be 0.97 and the Max as 1.03.
Looking back at previous tests, i notice the figure has gradually crept up over time, and wondering what this is telling me.
Does it mean the Lambda Sensor might be on its way out ?
It passed the MOT no problems at all, but they did say the emission test at 2.5k revs was totaly erratic, although perfect either side
It was good enough to pass fortunately, but im thinking of next year. Dont want to leave until the last minute to sort out again like i usually do lol.
Im wondering if this is linked in with the Lambda in some way, although it seems unlikely at just one point in the rev range.
Had the cat checked out and its working perfectly, and cant figure out why only 2.5k should cause erratic emission results.
