:hihi: Hi Everyone, I am a first time Mustang owner and I hope you all will not get tired of hearing from me or the dumb questions I ask. I have no experence with the modular style motors. I am a old man that loves working on older cars and trucks. I have no offical training just shade tree type :heha:. I purchase my 2006 Mustang GT used in Oct 2010 with a little over 52,000 miles on it, it had a few mods already done on it and I have had a few problems with it since then, but so far I have been able to work the problems out and the car is running great. I have done a little underhood dress-up mods and exterior mods to it. I have lived here in South Korea for a little over 18 years now and hopefully will be returning state side in a couple more years. :?: To get things started, here is my first dumb question; Sparkplugs: I went to change my plugs the other day, I pulled the coil-over, I looked down inside the well, there seems to be another sleeve or insert there over the sparkplug, I tried to pull this out with some needlenose pliers but they just slip off. How do you get this sleeve out? Hope this doesn't make me look too dumb! Thanks for any help provided.
