Re: Hmmmmm ???!!
car addict, do you have an ignition tester? (plugwire toucher blinker pen for lack of better laymans term)
try one of those on your wire.
it should blink.
duh. anyway i forgot the answer to your question, something that is quite common, its called spark plug compression failure, what appears good on the outside (the good ol ground on the head and look for blue) sometimes is alot different on the inside. Try a replacement spark plug like an NGK B6HS (or you can try a B5HS if you live up north more in canada, it is a hotter spark)
