Another helpful video. Hope your friends appreciate your work on their cars. Great to see you analysing the faults and solving the issues. Pity you didn't have your great X-tool D7 available for this job. Mind you don't lose your eyebrows using butane gas or brake cleaner 💥🤯

Thanks for your comment! I really enjoy the tinkering and learning. There's lots of great info here on TH-cam. My eyebrows survived intact too so that's a bonus! 😁

Always appreciated, thanks Boyce. :D

All that extra fuss.... Just spend a little more to get the right part.
You're also still seeing too much O2. Probably an exhaust manifold leak.

The universal one was about £50 and the car specific one was about £85. For an old car I didn't really want to spend much on it as it'll be off to the scrap heap soon I think. I quite enjoyed the fuss anyway 😁. Thanks for your comment and the tip about the possible exhaust manifold leak 👍
