man, not to sound all passimistic (sp?), but i was already there before and i know the symptoms. I replaced the car, rotor, spark plugs, spark plug wires, fuel filter, etc... Basically, a full tune up. heck, i even ran sea foam before all that. ran a tiny bit better. But after the next oil change, it was getting worse. so i pulled the upper plenum and saw washed gas on the manifold, thus the culprit being the CPI unit and nut kit.
