I'm new to this forum, so I hope you don't mind if I start by asking for help! My car (1994 skinny 1.8TS 8v) failed its MOT at the weekend on emmissions - the CO and HC figures are very high. I reckon it's running too rich - a very black tailpipe and an Oliver Reed-like drinking habit tend to support this. Is there anything obvious I can look for before booking it into my local specialists? Could the lambda probe be duff?
