Gentlemen,
Today I have been to a classic Car event looking for bits for my Rover P6 V8, found what I needed so when I got home I fitted the items. At the same time I fitted new plug leads I had bought last weekend to the engine and carefully took one off and fitted the new one before I moved onto the next cylinder, when I had finished I started the engine to find it running lumpy so checked all the leads and found all still sparking ok so I checked again, can someone explain to me how I managed to get two leads on the same bank incorrectly fitted to the plugs even though I did it one at a time cos I cant work it out :-))
