It's a 1.4 facelift. It kept lighting up the engine management light. That's why I've recorded the details, as yet the light had not come on in 200 miles.
First thing I replaced was the maf with a known working one. Light still came on.
So then replaced the 1st o2 sensor with a known working one. This video is since the ecu reset.
I have a used but good cat to go on next.
With regards to the long term fuel trim, that is the 23% gauge below the ft1x2 guage. I don't know what the 100% one is refering to.
