Hi my 2.1 petrol has failed on imisions will a new air filter and an aditive to the fuel to clean the injectors ect do the job

thanks

What were the results?? as its been known that the MOT tester has used the wrong limits.. should have given you the test results with limits they tested too..

Although there could be something wrong wit it too

A new air filter and "injector cleaner" may help lower it if there is a small gain to be had as would changing the oil and taking it down the bypass flat out in 3rd before taking it in for the test..

Hi it failed on the CO: 4.675% limit max 3.500% it also failed on the left hand drive headlights but I have managed to get the kit from brickworks

Thanks

When did it last have a jolly good service and set up?

Small tweak on the airflow meter prob required... as per haynes manual..

Hi had oil and filters changed 2000 miles ago

timng checked/set? Plugs? dizzy cap etc? if worn can affect emissions..

hi thanks it gives me a few things to try

My MOT tester is a local garage and the guy I try and get is a fan of old vehicles (he runs a SII LR). He let me use their gas tester to set up the CO properly the weekend before the test and it was as easy as twiddling the 5mm hex head in the AFM. That said, my engine is in good nick etc. I set mine at a little over 2% as I thought slightly richer would be kinder to the engine than slightly lean. (2% + or - 0.5% I think for wbx.)
