when i turn my a/c now my rpms drop to right before its about to cut off, if i turn it on max they pick up. all this is while sitting at idle. i havent ben driving it because my o/d light was blinking. my wife takes my truck to the shop to get the code read and now my engine acts up when the a/c is turned on.

does anyone have a suggestion?

also my gas peddle does not move freely, it sticks unitl you mash it a few times then it kinda works o.k., any suggestions?

 

I would check and clean your throttle body ( if you havent allready) as this can cause the sticky throttle.
