Hi Dave There are quite a few instances in the archives where strange engine management and driveability issues on various models have been traced to interference from spark plugs. Changing the brand of plug fitted, sometimes to "genuine", has cured the problem when all other logical diagnostic routes have failed. Regards, Steve
