Thanks all. AFM seems to check out and Ive played with the TPS as well without noticeable improvement. NI found a post from someone who had similar issues. He said that he found that 5th cylinder stopped firing after about 2000 rpms after car warmed up. I was curious so I checked. I have the same thing but on 1 and 2. He states that he replaced the ignition control unit and it solved the problem. Im going to see what that does.
