^ We only have contact with the owner, who had the car built by someone else, who had the engine built by someone else. I will try again to get the cam card.

What is a good test that I can perform to determine for sure if the idle restrictions are too small, other than o2 sensors? The plugs are not dark but they are not glazed white either.

Otherwise the car runs excellent as is, no off idle stumble, no light cruise surging.
