Screw it I will post emissions anyway.. lol

FIRST MOT - Fast Idle 1

CO - 0.543% (0.300% limit)
HC - 71ppm (<=200ppm limit) FINE
Lambda - 1.053 (0.970-1.030 limit)

Fast Idle 2

CO - 0.526%
HC - 73 FINE
Lambda - 1.208

Changed Cat (may have been dud) and Lambda Sensor (may have also been dud) and got rid of loads of exhaust blows..

SECOND MOT - Fast Idle 1

CO - 0.559% (0.300% limit) < Got WORSE?
HC - 73ppm (<=200ppm limit) Same, Fine
Lambda - 1.053 (1.030 limit) < Improved

Fast Idle 2

CO - 0.625 < Still WORSE?
HC - 96
Lambda - 1.036 (1.030 limit) < SO CLOSE!


How come my lambda improved, do you think it was the sensor change? Or just getting rid of all the exhaust blows / air leaks made it improve?

And why is my CO soooo high! Just CAT?

Please HELP!
