Just had my MOT done and it has failed on fast-idle emissions. The limit is 0.3% and it was reading in between 2% and 7%.

Having done a quick search on here, it appears to be a faulty lambda sensor that is causing this. A fault also seems to cause high fuel consumption, something I have noticed over the last few months.

Where can I get one for a '95 WRX?

Cheers,

Stewart

Halfords!!!

seriously they do a generic one for about £25 notes..

just make sure you make a decent crimp on the connections

...although when I went to Halfords and asked for one, the numpty looked at me as if I was talking Russian. :rolleyes: Ended up getting my Bosch from a motor factor called Mid West, for £25+vat.
