DG i think i had the same problem as you a couple monthes ago. I replaced my plugs with bosch platinum 4, and the car seemed to be running like crap. It felt like it was misfiring or something. Well i was too lazy to take the plugs out, and after a couple days the car was running fine. Just wondering how long you left your plugs in for?? Also i was talkin to some old timer today that knows pretty much everything about cars lol. Anway he said most cars never run right imediately after a tune up, something about the computer getting used to the plug...wasnt really payin attention.
