I have changed spark plugs on everything from weed eaters to helicopters but my 2001 GMC 4.8 PU has me stopped I can not for the life of me get the silly wires off of the plugs. Anyone got any tricks to do it. They are the ones that have a seperate coil for each plug and cover the entire plug with a steel heat shield over the whole thing. I tried twisting and pulling as hard as I could and haven't budged a one. I guess my last resort is to buy a new set of wires and cut the things off.
