hot start issues

99 c4 6 speed, when hot takes at least 30-40 seconds to fire up and then very low idle which takes another 10-15 secs. sometimes when it fires up it has no throttle response either. but shutting off and restarting again corrects that. To get it start quicker i have to fully press accelerator for 3-5 seconds and try to guess when its starting to avoid revving to much. I changed the crank sensor already to no avail . ONLY difference i noticed was the hot idle was a little better. it had been idleing around 600-650. now normal 850-900. I was thinking possibly throttle pos sensor but cant seem to locate it. unplugging MAF causes idle to drop so I believe its functioning properly. No codes and car runs great otherwise. a bit more complicated than my previous 83 SC.
