Now for the really stupid part. I changed to a fresh set of Champion plugs (the RN12YC copper cores) and the car runs fine again!!!

That low compression in #1 still worries me, but it's not lurching under boost anymore!! I can't believe that. I never would've guessed it was a bad/fouled plug.

Thank you GDonovan for giving my head a shake. Back to basics for sure. I feel like such a jackass right now.

I'll probably just drive the wheels off the ol gal until that #1 hole becomes a real problem then giver the full-meal-deal rebuild. She's too nice of a car to just throw away.


Thanks for letting me pick your guys brains in for three pages! That's why I love moparts and have been an annoyance here for over a decade!!
