A little back story. My ac vacuum line was never connected when I purchased my truck. I decided to disconnect the vacuum line from my Cruise control servo and use that line to my ac vacuum line since I don’t use Cruise control. To my surprise all my ac controls worked but now my truck is idling rough(much lower than usual) and smells like it’s running rich. This is even with my ac is turned off. I don’t believe I have a vacuum leak since all my ac controls and vents work.
Can the amount of vacuum that is pulled from my ac system (even though it’s off) cause my idle to drop and truck to run rich?
