It passed!!

I think the main things I did which helped were:

- A 15 min proper blast with plenty of redex in the tank
- A little bit of fresh fuel
- The battery was not charging so I fixed that. Voltage went from about 11V to 14.4V
- blocked a little hole opposite the lambda sensor in the exhaust.

Reading now 1.52% CO (pass 3.5%)
171ppm (pass 1200ppm)

Its now taxed and once the kids are in bed I am going for a drive!!





Track days ARE the best thing since sliced bread, until I get a supercharger that is!

Please read my ring story:

It would have been the exhaust hole. That lets o2 rich air in, the lambda sensor sees that o2 and ECU interprets that as a weak mixture and richens the fueling... but still sees the leaking in o2, so richens more... and again...

Anyway, well done.
