10MM extended socket and 6" extension bar needed, I changed my plugs today. I have had a few problems with the car like missfire No2 cylinder, then the engine management light coming on then going off when i put a better grade fuel in only for it to come on again
so I changed the plugs and two HT leads, WOW engine management light went off so I pulled away gave it a bit of gas UUmmm no problems so I wellied it
Fantastic no lights on the display and not a single hic burp or f@rt, Sooooooooo happy now, I hope you get yours sorted, the old plugs were champion( garage man says they are cr@p) put in NGK.
