I have an issue with removing the last spark plug. I have the normal spark plugs on this vehicle. The issue I am having is with the one located on the passenger side near the firewall. It seems like something is stuck or jammed next to it. Plastic maybe. Yes, I blew out before removing the boot and after. I have made several attempts to remove it. The socket will not fit on it. I have tried to use a pick to remove the item, Dremel bit (wont fit down in tube), WD40, fingernail polish remover, etc. A friend of mine suggests heating up the socket and see if it will melt the plastic. If its plastic. I am thinking just run the Exp until the engine is hot. Its located to where you cant see anything unless you use a mirror and a flashlight. Any help?
