Ok I had the Nova in for the NCT or MOT in the UK. It a 1993 GSi with a CAT Converter. It was in the same time last year and passed on the emissions no problem.
Last years reading was 2.99% but this year it is 9.99%.
The Hydrocarbons last year were 209ppm but this year are 942ppm.
There is also are brake imbalance in the rear of 47%, nearside 1.24kn - offside .660kn. So I guess that is a sticking rear brake hub?
So I need to know what to do to pass it?
Why the emissions were so high as compared to last year?
The car has not been driven much since this time last year. It gets the odd run but that was it, as I was too busy for driving it.
All help and ideas would be much appreciated
