Well as some folk know my old e28 passed its fiirst Mot in 8 years other day. Im a bit confused with the emission results tho so any thought would be appreciated
Heres the cert
that pics not the best so this is the figures
Description Max limit Actual Value Pass/ Fail
CO % vol: 3.500 6.242 Fail
HC ppm vol: 1200 201 Pass
Idle speed Pass
Smoke level Pass
Overall Result Fail
I still got a pass on the Mot with no advisories tho. Mot tester mustve felt sorry for me having an old machine like that
Any ideas on the high HC results guys?
I think its got a slight misfire and im gonna change the dizzy cap and rotor arm. Right direction do you think?
Its got new oil in it, plugs and air filter and coolant
Edit: Sorry, i meant the high CO
