Take the blue wire that the oxygen sensor should connect to and connect this to a known earthpoint, like the battery negative post. The dwell reading on your metre should read 10-15 degrees.
I have connected the blue wire that should be connect to the Lambda sensor to a negative point, and it doesn't change anything.

I'm unable to find any leak from the red line and they're attached correctly.

Otherwise sounds like a bad cpu if it's not oscillating or the full throttle microwswitch doesn't make the dwell go to a steady 54 , Nick sorted mine and it's running better than ever !
Yes, the two screw were misaligned and the micro switch wasn't able to be fully open.
Now this is good.
So, I made another video and i thought it was fine...
Nevertheless, 31 minutes later another thing happen, the iddle goes to 1500rpm a few seconds and then go down to 900rpm
For now, I stopped the investigation, I will try this week-end...
Video will be posted once they're ready on YouTube.
Thanks again for your help
