Thanks guys, sorted, reason for the change is that the car wasn't starting and i thought it was the plugs, turns out it wasn't, the car still won't start :( Its turning over as if it was gonna start but doesn't fire, had a new battery on plus the plugs but still no joy, anyone have any ideas what my next step is?? Wanna try and sort this myself before taking it to a mechanic's and shelling out loads of dosh! Cheers again
