Hey,
I've got a 94 SPi which I've owned for 20 years, I usually tax it during the summer months put a few hundred miles on it then its tucked away for another year, it runs fine but i've always thought it was fairly rich, after a brief drive the cabin would smell of petrol and your clothes stink all day but maybe I keep forgetting this is the joy of a mini? Anyway I recently purchased a diag cable after it was recommended on this forum (ebay + android app), It reported back a faulty coolant, air inlet and map sensor which may account for the rich running however the figures the app gives out appear to be correct so could these be old fault codes that have never been cleared, is that how the MEMS system works? I've not replaced these in the years i've owned the car so maybe it is a true fault.
Images from reader attached, if anything looks odd with the figures id love to know what you think.
Cheers all and glad this community is still going.
Pete
