Had a problem with my '03 Z involving loss of accelerator function when I pulled up to a stop light. After the light changed to green, when I moved back from brake to gas pedal, the car would not move. No revs at all but I still had power. Had to put it into park, turn off the engine, restart it and only then was I able to drive normally. This has happened a few times over the past month. Haven't had a technician look at it yet. Would appreciate anyone letting me know if the have had similar problems and what the cause ended up being. Thank you for your help.

 

That's your problem.
