plug extenders

[paul2000]

HI lad,s can any of you help me out ,i have changed the extenders for socks but since i have changed them the car sometimes takes a while to fire up ,sometime will not fire at all,if you do away with the extenders do you have to change to another type of plug ,any help would be great as i don,t want to put the plug extenders back on , many thanks paul
