Strange but true . . . I have no idea what was wrong! I started the car up one morning and it was running fine. That issue has never shown up again (and I hope to hell it doesn't). Then I found the issue with my 62mm supercharger pulley slipping at high RPM and I installed a new 65mm pulley. EVERYTHING is great now! I'm actually starting to enjoy the car again and I'm driving it more often than ever! Just need to tweak the sound system and thinking about doing something with that river of silver on the center console.
