O.k. I finally had a little time to check the plugs and they looked fine. I changed them out with the ngk iridium plugs anyway. I also cleaned my mass air sensor with the crc mass air cleaner and cleaned out my throttle body. I replaced a cracked hose that went from a part of the stock air box, to the valve cover. Connected the battery and fired her up, no cel. Let it reach warm temp, and then I beat the **** out of it from every stop. Still no cel. I only had time to run the car for like 15 min. I'll check again sometime tomorrow, when I'm sober...lol

If anyone has any input, please feel free to post. I don't think what I have done has solved the problem.....just a gut feeling.

Looks like you have a misfiring problem in multiple cylinders. Check your ignition system starting off with the spark plugs.

Have you verified correct valve timing?

No, I was looking for the easy way out. Since time and my job is a limiting factor right now, I've done the easiest. I hardly drive this car, as is evident by the little mileage I've put on it since last year (5k and a little change). I am going to bring it back to the dealer as soon as I get some free time from work. I'll post back...
