You sound like a candidate for some combustion chamber cleaner and a run in with some MAF cleaner as well.
That has all been done.
Bizarre.......
What CC cleaner did you use?
SeaFoam, Berryman's B12, hot water, Amsoil Power Foam, Carb cleaner. I've also run several bottles of Gumout Regane.
The car runs great, as long as I use premium.
Holy!!! Quite bizarre, since obviously the car isn't supposed to.
What year is it?
It's a 96 P71
Ahhh, so no knock sensor IIRC, correct? That explains a lot.....
