Hi,
My car has just failed its MOT on exhaust emissions.
The acceptable lambda range is listed as between 0.97 and 1.03.
My car tested at Lambda 1.06.
The test is listed as High Idle (3,071rpm) ,it appears to have passed the low idle (680 rpm)
I have no lights on the dash and have connected up my ODB reader (Torque Andriod) and have no codes stored on the car.
I would be very gratefull if anyone can point me in the direction as to what my problem may be, as I dont want to spend a fortune on the car at a dealer if at all possible.
In the past three months I changed all the spark plugs and coils packs and the car has covered 6000km with no faults.
I presume it is safe to continue driving the car?
Thanks!
