Thanks for the help guys. I'm cleaning my K&N as I write this. I also found a very loose connection between the air box and the throttle body. I tightened that up and once I get the filter in, I'll let you know. O2 sensor was also suggested by another person, so I'll check into that.

If I do in fact need to replace the O2 sensor, where is it?

o2 sensors dont go bad that often. Follow the exaust from the header. somewhere after the pipes come together and before the first cat you'll find what looks like a 22mm spark plug with a couple wires going into it.
What kind of gas does she run in the car? how many miles on it? You might want to spend some time whan the engines cold tracing all the vacume lines to locate any broken or cracked rubber hoses. Another cheap thing to try is the fuel filter. $22 at kragen and should be changed every 25-35k.

Thanks for the suggestions. The car is currently at the dealership getting checked out. My mother-in-law is coming this weekend and the car has to be up and running. No time for me to play mechanic It'll be interesting to see what they come up with.
