hi guys!!!!

i just discover problem with my truck. well is like this. first when i'm on idle and push gas it flaps but not everytime only does it sometimes and sometimes my engine shuts off.

could it be belt problem? because when i turn on AC. my rpm goes up and down on park. and when i press gas paddle i loose power i mean my rpm goes down below 500 and engine shuts off.

could it be belt and pulley problem?
