Maybe check the vacuum lines as I recently had this same sort of condition, finally tracked it down to the large ducts leading from the air cleaner assembly to the throttle body. Due a bad PCV oil leaked into this duct and softened part of it where two other air flow lines fit, giving me MIL of multiple cylinder misfires and a lean bank 1, lean bank 2code. The PCV, its grommet through the valve cover as well as its hose assembly have also been known to simulate cylinder misfires.
Thank you fro your response... was your issue happening at random times.. mine is coming and going... for a couple days it will be fine... then all of a sudden the car will start shaking because two cylinders are misfiring... to the point where then engine light will go off by itself for a while then reappear...

P.S. just read your old posts... mine doesnt necesary stop if i just restart... once the engine warms is usually when it goes away... meaning as long as half an hour til it starts to get better
