It is too tight. That microswitch tells the fuel system you have the throttle closed and that then brings the idle down to the normal level. If you are not hitting the Downshift Switch you are most likely not hitting the WOT Switch on the throttle body either so you are not enjoying the extra fuel enrichment cause by that switch being engaged either. Set you throttle cable the proper way, which in the quick and dirty method is as follows. First loosen it so that it activates that switch on the linkage. Then have someone push the throttle down to just before activating the kickdown switch. It should now have the throttle plate open fully and engaging the WOT switch while the spring will allow for the kickdown to be depressed. You can tell the throttle is open by seeing if the throttle linkage can go any further by hand. If it still has room to go then you will need to adjust the portion of the cable at the actual gas pedal in the car.
