Hiya. I just bought the wife a 145 1.8 TS and whilst trying to sort out the usual idle issues I replaced the Lambda as a precaution, only to find another Lambda connector just hanging about with no where to go. The one I replaced was the one on the cat under the floorpan, this new one is the pre cat lambda harness....but where does it plug into? I'm almost sure it won't cure my idle issues but not being connected isn't helping any. I have tried a new MAF, cleaned out the TB, done a reset....all to no avail. I suppose the stepper motor is the next step then?
Many thanks
