This may seem a simple problem, but I bought some
new plugs, then went home to install them.
Problem is, I can't get the spark plug connectors
off! The manual says to twist them, ya, right.
I just did mine and found that using pliers helps tremendously. You need to grip the heat shield on the edge so you don't crush it but this gives you a better grip than trying to use your hands.
Whatever you do,do not try to remove them by pulling on the wires. That is guaranteed to rip them apart from the shield. (I did but I was replacing the wires anyway...)
Here's a little secret that I stumbled onto when I changed mine. ;) If you have the stock wires that you want to remove....notice that there is an 11/16 in, hex molded into the end of the boot.
Take an oxygen sensor socket (has a slit in the side for the wire to protrude) and slip it over the hex of the boot and twist away. :) If necessary place an open end wrench on the hex of the oxygen socket.
Unforturnately I was on the last plug before I figured out this procedure :cry .....but it worked great on #1.
For me it was a matter of "pull harder than I really thought was safe" to get them off. They feel tight as hell, but twisting and pulling at the same time will get them to eventually wriggle off. Same thing for taking out the plugs - I thought I was going to seriously break something putting that much force on the plugs, but at a certain level they just came loose. If you're like me, and it's the first time you're really doing anything to the engine, it's disconcerting to have to use so much force on these things :)
