range, sometimes in park, help? V8 engine, idle a lil rough, has stalled when parking, not often
 
ide say take it to autozone and let them run a free computer scan, dont resolve every problem but should put you on the right track. my guess is the : AIC air idle control valve is stuck or the TPS Throtle Position Sensor is WooPeD... just a guess
 
whens the last time it was tunned up? possible need tune up check the air filter also if all this is good check this site it will help you
