Right so I failed the NCT on saturday, emissions and number plates. The number plates i can figure out but can someone give me an idea of what i need to do to sort out the emissions.
Data was as follows at 3000rpm:
Lamba: 0.991 (Should be 0.97 - 1.03) spot on
CO: 0.70 vol% (should be less than 0.30 vol%) FAIL!
HC 62 ppm (should be less than 200ppm) spot on
Any ideas lads?
