ok, so i own a 04 TB LS,55k miles. now whenever i put on my a/c or defroster,the truck starts idle really low then the idle will go back up ( i guess when the a/c compressor clutch clicks off ). it will continue to do this up and down idle and the truck will bronco too until the idle gets low enough to shut dwn the truck, also feels like i'm loosing power when this is happening

HELP

Read the link and then clean your throttle body and remove the neg battery cable for 35+min. Should take care of it.

If it doesnt, then have the dealer reflash and upgrade your PCM software to the most current version.
