not to say we told you so, but you did buy a modded car that you dont know jack about.

I bet its hurting more than you know.

Like your tap shift stuff, I bet that was screwd up with the so called tune it has or with some shotty wiring or whatever.

And now with these plugs, it "could" be bad plugs, but the likelyhood of you getting 3 bad front plugs is far fetched.

Its gotta be more than just a plug issue your dealing with.
