Car would not hold closed loop this morning, but it did register for a little while. Not so happy with it so.
I bit the bullet and spent the better part of 7 hours changing out the o2 sensor, the old one came out but brought a fair anount of cast iron with it. So I removed the exhst manifold and tapped it clean. Seems ok, no leak and went in pretty tight so Iam hoping for the best. First time getting that far into any car, all in all, went pretty well.
All back together and it seems to have a little bit better acceleration, LTFT was quite steady around +8 to +12 STFT was hanging around -3 to +3. O2B1S1 fluctuating nicely.
This little Autel scanner just makes me want to upgrade to something that can track fuel consumption, access more information if possible and store more data on a hard drive.
This x90 takes a real beating up here, with 5 drivers and a minimum of 3 cold starts per day and a short 15km commute 3 times a day. Average annual temp is -16. All gravel or ice road depending on the season so its pretty bumpy. Car had 160,000kms when it arrived in august 2012 now its up to 192000. I just stated taking maintenance of the thing seriously when it was almost too late. Hard life for a 17 year old car for sure.
