Hi, all.
Just picked up a 2001 Pontiac Grand Prix GTP Special Edition coupe.
It seems... "sluggish" compared to what I would have expected. Runs fine, no hesitation or rough idling, goes into boost when you step on it, but I've driven a Chrysler Town & Country with a NA 3.8L (215 hp) that feels a bit peppier, at least under normal driving conditions (haven't gone WOT on the minivan.)
I've read I should look into clogged cats and badly adjusted bypass valves. Any other ideas, or comments on those?
Still not sure this isn't just my perception of the car based on one day of driving. I'll be hooking up my OBD adapter soon and logging some data while driving.
