I need help! One of the spark plugs on my 2000 GT backed out. The Threading was stripped when it came out and now I can't get another plug in. A friend told me about this thing called a "Helicoil". He was kinda sketchy on the details but I got the gist of it. Has anyone tried this? Will the shavings mess up the engine? Is this a temporary fix or will it last for a while? Will I lose any power? Money is an issue and I would like to save money if possible, but not at the expense of ruining the engine.
