1st gear to 2nd gear car will shake/splutter around 16 mph, 2nd to 3rd car will shake/splutter and so on basically every gear. Um around 5 gear going about 50 mph and I add some what amount of more gas it will shake/splutter. If i am in 5th gear and going over 60 mph and step on it seems fine. First thing i noticed was that one day started my car like normal and turned the AC on idle acted weird like stalling and then rev up and down a little and then engine stalled out I have switched out egr valves, new egr modulator, switched out throttle bodes and iac valves, PCV valve is 3 months old. At a lost right now car just seating to scared to driver her any ideas. One more thing when i start her up the oil light comes on for a second and then goes away everytime i dont know if that is normal. Is clutch slipping or transmission going?

Easy way to test the clutch is to get up to 30 mph and throw it into fifth. Then floor it and see if the RPM goes up with speed smoothly. If the RPM goes up without gaining speed it's slipping. Almost sounds like a vacuum issue.
