Engine has miss at random RPMS and is noticeable when starting off with light throttle. Is also noticeable in left handed curves. While vehicle is in Park and idling you can rock the body from side to side and the engine will miss, it does it more when the drivers side of the body is going down and the pass side is going up. Fuel injectors seem to be spraying good. Have changed the oxygen sensor and the MAP sensor. Any ideas...Thank You

It sounds to me like a plug wire is grounding out on something. Check all your plug wires to see if you have any rubbing on metal somewhere.
