My 94 Xj81 just got motd after sitting nearly a year. The car was in good running order when parked but has developed over time a habit of stalling when idle, and often only running at 300-400 rpm when cold. Once warm it’s all good, and the car idles at 620 rpm. No VCM code. Now the check engine light has come on, and I have done a bit of research.
A culprit seems to be the o2 sensors.i cannot find any ,material on how to replace those on a xj81 let alone how many there are. 2 or 4? How complicated is it to change those?
After having spent 110€ on trying to gas up my ac system, and having a leak on the compressor I am not in the mood to experiment to much with spare parts.
I know there can be plenty of other causes to the problem, but I think the o2 sensors are a good guess.
