The cat warning light on my 1993 1360cc petrol 205 is showing intermittently, and tickover is erratic. Is this a failed cat? or oxygen sensor? or what? Opinions gratefully received!

Hugh - the 'K-light' has come on a couple of times since I got my '93 GTx 20 months ago; and gone out again without any noticeable problem. I don't think it can be the cat as I don't think it 'knows' anything about the state of the cat. More likely to be an ECU problem (e.g.a contact) IMHO.

If the warning light has come on the computer should have logged a fault code, which can be read by a suitably equipped garage. Unlikely to be the cat, and this won't show up directly as it is not monitored might show as a lambda fault though. Best to get it checked out before you do damage the cat or something!
