Hi guys, Ever since I got my 2013 8V Stelvio last year it has had a tendency to cough on overrun and was a lumpy idle. I changed the map to one from Beetle and that improved it and smoothed out the performance overall, and at the same time I re-set the low speed balance as per the instructions etc., but it still does it and while it will idle when cold, once it gets hot, or idles for a while, (around 1100 revs) it tends to try to drop a cylinder, so I have to keep a hand on the throttle at the stop signs and goose it occasionally. I read on another site about someone having a problem on a 1400 Cal., with too much oil in the crankcase leading to oil in the air box and ultimately on the Lambda sensor on a 1400. Pete R. had warned me to only fill the crank to ⅓ of the dipstick and I did that, but when I checked in the airbox, there was a bit of creme in the right hand cylinder intake trumpet, but minimal oil in the box itself. None of this is a major problem, but I would like to cure the problem, rather than simply turning up the slow running and ignoring the minor amounts of spitting on over run. So first off where is the lambda sensor on this bike and how do I clean it and is this a likely culprit? Otherwise what else should I be looking at? Thanks in advance. LangleyMalc
