Hot start issue

Hey guys n gals, I've got an S4 GXL, it drives fine when I start it in the morning, but as soon as I get it to operating temperature, then park it for 5 minutes, I have to give it gas and hold the rpms up, otherwise it stalls. I've adjusted the tps several times, and I installed a wideband o2 so I can see I'm not running too rich or too lean. I've sprayed brake clean, but can't find a vacuum leak, and now I've stayed messing with the throttle plate adjustment and the variable R/L resistor and when I let off the throttle, the rpms dip down and it almost stalls. I may have messed the settings a bit too much, and I'm not exactly sure what the exact settings should be. Any ideas or help would be greatly appreciated. Thanks in advance.

First off, look at the FSM to adjust the throttle and variable resistor, than go from there

Have you looked into possible intake or exhaust leaks?
