I too have a 93 GP 3.1L V6. My car has been a rough idler for as long as I've had it. I reciently had it in for a Pennzoil 10 minute oil change. I have the air filter and oil filter replaced but the guy told me my oil was like tar. Apparently they preform a reasonibly priced chemical flush. This takes no more then 15 minutes. The car runs like a champ now.
