    since I've done lim gaskets, new (stock..bosch wires I believe) and new ngk iridium plugs, I've noticed a slight shutter when starting to accelerate. Even in park it does it. Not a motor mount, and everything was done by a certified gm mechanic that has hundreds of lim gaskets so im confident the procedure was done correctly. Im wondering if those plugs are creating the problem? Its not a huge problem, but something I've noticed since the change.

    As stated above, iridums are notorious for issues in 3800s.

    U gh! Figures. Alright, ill try changing them. What's a really good plug? I've heard about the autolite 104's, but isnt that only for modded cars? I should've known better than to listen to the guy at autozone when he said "these are comparible to stock replacement". Lol btw, I've only got a hai w/ a 9" spectre cone filter. Not really a mod, more like a necessity! Lol
