Well the stumping is over. I had low fuel pressure so I dropped the tank & replaced the fuel pump. That did not fix the problem. I was looking at the car today and trying to figure what would make this thing stutter & stumble etc... after it was warmed up, but not trip the check engine light or throw a code for the scanner. The book had all kinds of suggestions, but they should have all thrown codes. Just out of curiousity, I took the PCV valve out and shook it. It did not rattle. I cleaned it with carb cleaner until rattled. I put it back in and took the car far a drive. I didn't think it was going to work, But guess what, it did. She runs fine now. Had her up to 80mph & no stumble or chugging etc... Who would have thought it, but that was the problem. Thanks to everyone who responded.
