Ford Fiesta 'V Reg' Ghia 1.1 litre?
Chugging when driving. Okay when it is cold but soon as it gets warm it is as though it is firing on 3 and not all 4 spark plugs - Please can anyone advise as I think I may need some copper spark plug leads. I have placed some new bosch spark plugs in with copper centre, no oil leaking anywhere so baffled - Your help is appreciated
