Hello all,
Had my MOT yesterday and it passed on everything and only just managed to pass on emissions..(same old weak spot on these cars).
Now, i put a new NTK lambda on the day before the MOT and filled up with Optimax.
Fuel system was cleaned out using Slick50 last month. No issues or problems apart from the bouncing revs @ 2k where engine judders when holding @ 2k. CAT is also fine and car drives fine overall and fuel consumption is average.
The examiner said its down to the larger exhaust I have on the car (2 box Ragazzon from cat back) as it is a larger bore and will affect the mixture and emissions overall.
QUESTION: Is there anything I can do the correct the mixture and keep the emissions down? When its idleing there is a stronger than normal smell of petrol fumes.
Oh, Its had a new BOSCH maf, air filter, plugs, temp/sender & stat + all the BBOB has been prof rewired - no errors.
Car is a 2000 145 QV - All standard apart from exhaust.
Any help appreciated.
Thanks
