Went for the M.O.T this morning, raining hard, heat blowers on full... Lovely!!
I arrived at the MOT station fairly confident It was going to go through without any problems but no..... not today. I'd bought the car as an mot failure and have been working over the last month getting it all sorted... to address the previous emissions issue I've tried an air filter change and a new exhaust as the old one was knackered, and in two pieces when I got the car.
Exhaust emissions carbon monoxide content after second fast idle excessive [7.3.D.4]
Fast Idle test
CO - 0.49% FAIL
HC - 31 ppm PASS
Lambda - 0.99 PASS
Second fast idle test
CO 0.49% FAIL
HC 31 ppm PASS
Lambda 0.99 PASS
Natural idle test
CO 0.42 PASS
These new readings are actually HIGHER than the previous readings taken on the MOT just before I took ownership of the car, on that one it was failing at 0.43 CO on the fast idle test and second fast idle test.
I'm pretty new to all this but I think It's looking like a new cat or lambda...
how do I test the lambda sensor?
