Failing MOT emissions test at fast idle CO 0.48%, HC 28 Lambda 0.987, no faults or fault codes found.
Catalytic converter replaced, extended Forté Advanced Formula Motor Flush carried out and Forté Petrol Specialist Injector Cleaner added and extended road test carried out, fault not cured. After further investigation it was found that the vehicle was fitted with three catalytic converters.
The fault was cured by replacing the two catalytic converters in front of the manifold, emissions retested and passed.
Thanks to Dave at Autopics Ltd in Rustington, West Sussex.
Forté's Technical Helpline receives over 300 calls per month. This blog shares solutions for garage workshops on common driveability concerns that can be quickly and effectively treated. The vast majority of those identified are caused by fuel and oil borne contamination formed by natural degradation or via the combustion process. This is a fact of life for internal combustion engines where fossil fuels and oils are used.
