O.K. when you adjust the T.V.cable you push the D button in and slide the cable flush and then let go the D button and pull the throttle all the way open and you should hear a click meaning that it is reset right. now if I leave it at this adjustment (cable seated flush) car shift hard, so when I make another adjustment I know i have adjust the slider but do I have to also open the throttle wide open again after I set the slider or is opening the throttle wide open a one time thing.
