Thanks for the advice -- I'll change the plugs and boots and hope that helps.

Also, I've never liked that fake air scoop. It serves no purpose other than catch water when its washed and streaking the hood no matter how well you dry it. Maybe when I get the car repainted I'll have it removed, and fabricate something that looks more like the original '68 GT.

Pray that at 186,000 the plugs will come out! I never let plugs go more than 50,000 on the daily drivers despite them being "good" for 100K. I have seen more than a few busted plugs or stripped aluminum heads from plugs that had welded themselves into the alloy heads.

And use some never-sieze on the new ones despite the "anti-sieze" allegedly on the new plugs.
