would be interested if anybody has experienced this problem. The engine in my caterham is a 1.8 Vauxhall 8 valve The number one cylinder is not working although the plugs are ok.. the leads check out and fuel is getting into the cylinder and the compression is up in line with the rest of the cylinders Also there is a good spark to the number one cylinder. Engine runs on 3 nothing from No1 completely dead doesn’t fire at all
