I have a 50th anniversary V8 Defender 90 and up until recently she purred as smooth as Pussy Galore. I must have upset her because she has lost her rhythmic purr and instead feels as if she may not be firing on all cylinders. She idles a little rough, especially from cold. If I run her for a while and turn off the engine, it generally now takes 2-3 turns to get her to fire. When she does fire its not instantaneous.....more like a slow delayed fire. Kind of like when you try to start a car that hasn't been started for a long time when it finally comes to life slowing picking up revs.......like that.
Anyway, I have a cheap diagnostics tool and checked for codes, but none were shown. However, I did notice the following:
02 Bank1 Sensor1 - 02 Transitions(s)
The measurement is way higher than the max.
I did a bit of reading and I believe this may be an 02 sensor for cylinders 1.4?
Thanks in advance for any pointers, hints or solutions.
