The lambda sensors makes sense, as I know they go suddenly. It is running better with the old Champion plugs with a 40 thou plug gap and they might cope better with over fuelling than the rather tatty looking Iridiums. I have added a pair of Lambda sensors to my Brands Hatch Morgan order. So if I have replaced coil pack, leads, plugs and lambda sensors, hopefully that will keep me going for another few years or at least until the fuel pump dies. I just hope that Bozo the Clown's quarantine clamp down for France does not wreck the post/courier services even worse than they are at present. I have already been caught on this, when I bought a rare Leica historic lens from New Zealand, only for it to get stuck as quarantine set in and all flights were cancelled. It sat for two months at Auckland Airport then vanished. It turned out the sender had not insured it properly either, but only by weight, which was about a third of its value.
