Hello again distinguished members. Well as many of you may know. I had a idle issue after a battery change out. Would not do a TPS reset. I installed a new O2 sensor. Still no results So she went to the local BMW dealer. He reset the TVA. Now she runs great. I also just installed a set of Avon 3DXM Storm 3's . Great tire Wow.. Sticky. Only thing I noticed was me and my wife were out yesterday. And in the middle of a left turn,I hit a tar snake. It unsettled the LT just enough,You know.. To make your butt pucker. Well. It was 93° out under a hot sun and probably softened the tar. So I'm not reading to much into that now. Anyway. Give them 2 thumbs up so far.I do now notice after the O2-sensor replacement. I do not get anymore black soot on my muffler. And no more of the occasional smoke on startup. Have noticed the mpg is slow to recover.It's creeping up slowly yesterday after a fill up. It rose to 34.5 from 31-32.5. May need to reset BC computer. But I have a zumo 550. I can track mileage with that. Will see if mpg improves.
