R56 Mini First (1.4) lumpy idle
My wife has a 59 plate Mini First which had elevated HC readings at the last MOT, but the re-test just scraped under 200 ppm.
Her Mini has started idling lumpily (~650 - 700 rpm) and sounding a little raspy at low revs (< 2500).
I stuck my OBD cable on this evening and the o2 sensor seemed to be reading < 1v which seems a little low to me, I was expecting >= 1.5v (see attached*)
After reading h t t p://w w w.mini2.com/forum/second-generation-faults-fixes/206833-mini-failed-emissions-test-second-time.html I'm tempted to get some cleaner for the cat, but are my o2 readings out of whack or am I miss-reading them?
