Just took my glanza for mot and all was fine except emissions.. On all tests the CO was about 6.5 - 7% and the lambda was 0.82.... Both fails, but HC passed (just - by 4ppm!!) any thoughts would be good I'm thinking boost leak, or too high fuel pressure or timing?! It's got fuel pump, fpr, cat was fitted, ct9 turbo, runs a little rich on low rpm and a bit lean on high rpm.. Had a lot of stress with the car recently, and was hoping it'd go we'll for a change! Not driven the car for a month and a half!
