My car has a very rough idle in drive but is just fine in neutral

(1996 Ford Taurus)
in Park Ridge, IL on January 30, 2014
My car has a very rough idle in drive but is just fine in neutral, it idles around 500 rpm but when it is in neutral it is 750 rpm. New spark plugs, wires, air filter, fuel filter, cleaned throttle body and replaced IAC And PCV. Any Thoughts? Motor Mounts are fine only happens at stops in drive or reverse no codes
