seems to be an ongoing debate. you need at least platinum on that engine to make it run good. wires are tough i used to buy nothing but delphi or delco but now they seem as bad as the cheap Chinese ones. i bought the middle range autozone ones a couple times with pretty good luck.

Well I changed the spark plugs and wires...didn't help. I've been researching online and some possibilities are a fuel issue (filter, pump, etc.) or bad ignition coil packs. I changed the fuel filter (didn't help) but I'm sure it needed it anyway. I'll probably just take it in again and hope it acts up for the mechanic.
