I have a 2005 kia sportage lx, 2.7L V6 engine and i would like to know the procedure on how to check for vacuum leaks''....Also, Is there a way to tune down the idling on our kia truck's. Thank's and i really appreciate everyone's time
One way is with a can of aerostart (contact cleaner or any other atomised metho like cleaner) and spray it around the areas a little bit at a time, listening for a change in idle rpm - most likely going up.
First up, check all your connections and clamps. Also ensure all manifold bolts are tight.
