MOT Emissions Failure - Help
My 96UK just failed its MOT on the fast idle emissions test with the following readings
Engine Speed: 2839 rpm
CO Level: 0.00%
HC Level: 3 ppm
Lambda: 1.09
on the second test it failed again with a Lambda of 1.08.
What is the most likely cause of this?
One's I've seen mentioned are
1/ Air leak
2/ Lambda Sensor
3/ MAF Sensor
Is there any way I can tell which of these is the problem?
