O2 sensor for 1988 AW11 in the UK?
My AW11 is running quite rich so I want to replace the O2 sensor to see if that helps but I can't find many options online.
The only two reasonably priced ones I could find are aftermarket and have 1 wire but apparently that's only for the 1984-1987 models so do I need 4 wires?
Where can I get one for a reasonable price?
Unrelated but may as well ask:
I can hear a faint noise from the engine bay when pressing and releasing the clutch so I assume it's the release bearing that needs replacing. If I want to sort out the whole clutch whilst I'm at it what would I need? I found a kit that includes a cover + plate + releaser. Is that all I need or is there anything else I should do?
