Hi can anybody help? I spent just over a grand 2 months or so ago on a new cat, lam sensors, MAF unit etc. put the car away in a lock up until required for the summer months and starting it up once a week let it run until warm etc. it was taken in for its MOT so as to be ready to tax it on the 1st of July only to be told its failed on emissions if its had new sensors etc, what else can it be?

How far off was it?
Could be that the garage starts and no prolonged run has left deposits in the exhaust system that need to burnt out (especially in the cat which needs to get quite hot to get it working right)
