help with getting the spark plugs out. Is there some trick to it. I have tried to pull the plug caps off and they won't move. Do they have to be turned, I have tried that 1/2 & 1/4 turns each way but still no go. And they are hell to get to. Is there a special tool?

I don't know of any procedure to ease the removal of the plug wires. I destroyed a set of wires a few months ago when changing the plugs. You might try warming the engine up and carefully trying to remove the wires, but be sure to let the engine cool down before attempting to remove the plugs. I ended up removing the valve covers in order to get the broken pieces of plug wires out of the holes in the heads. The plugs are much easier to remove with the valve covers removed.

 

I wonder what sort of lubricant could be put on the plug wires to ease their removal next time? Anti-seize, silicone, oil, grease???

 

Be sure to put a little anti-seize on the threads of the new plugs.

White dielectric grease is usually recommended on the wires boot to ease their future removal. Usually available in a small tube in auto parts stores. This grease can also be used on other kinds of electrical connections to protect them from water and corrosion.

That seems so obvious now!!

 

I have been putting the dielectric grease in the center of the wire where the plug goes, but what was sticking in my case was the outside of the black plastic piece that sticks into the head. It was ferociously stuck. I just stuck an old set of wires on there temporarily until I buy new wires, I'll try the dielectric on the outside next time.

The trick to removing spark plug wires from the spark plugs is being able to get your hands in there to begin with. Did you remove the windshield washer fluid tank on the driver's side and remove the air box assembly on the passenger side? On the driver's side, it also helps if the fuel filter bracket assembly is unbolted from the strut tower.
