front O2 sensor received and replaced..
wont have a real tangible idea of difference to mpg until a good week of driving but it made some very minor changes to the fuelling, and to pre/post cat readings. not really a lot but then every little bit helps I suppose before: after: has anyone else got any suggestions as to why my fuel trims are showing plus figures. or maybe a confirmation that those readings are totally fine? this is all at idle but I revved for a bit and the fuelling didnt seem to change. I'll check again next week but my understanding is 'long term' is only like 20 seconds or so beyond that really I'm happy to just leave it alone now, pending a test out on the longer roads it seems to be running perfectly. to drive it's smooth as silk and pulls well no hesitancy Last edited by stuart bowes; May 24th, 2021 at 21:15. |
