Spankey,
I was having the same kinda problems. It would stutter and sometimes pop out of the intake. Not throwing any codes, but I took it by Autozone to get any codes pulled. I got p 0174(Bank two lean) which means the lower front o2 sensor is bad. I replaced it, still same problems. A few days later is when I noticed oil in the water. I'm not sure if it's all related, since I haven't had any problems driving the car. No noticeable loss in compression or anything else for that matter. I dropped it off yesterday and it's gonna be expensive. Don't mean to scare ya, but it sounds like me all over.
Mike
