My vehicle just failed an MOT emissions test, on the Hydrocarbons, not the CO2. Apart from adjusting the fuel/air mixture, what can I do to ensure that it will pass when I get it re-tested. Would tuning it help? I think I was told that misfiring could be causing it. What is the high Hydrocarbon reading indicitive of? The vehicle in question is a 1986 Bedford CF2 Ambulance. Cheers.
