'89 900T Idle, Flooding, and Hesitation Problems

I need help diagnosing a series of intermittant problems with my '89 900T. I have had intermittant high idle problems for some time and have chaised vacuum leaks. Have checked all obvious vacuum lines, have replaced the AIC motor, have replaced the fuel pressure regulator, have replaced the APC solenoid valve, and am now suspect of the coolant temperature sensor. Several months ago I began to have an inexplicable but only occasional flooding problem. After running well and shutting down for a couple hours, the car might not start readily because of apparent flooding. Most recently have had a problem with hesitation again intermittantly. Car seems not to get gas when I open the throttle. Have done fuel pressure check and continuity check on throttle position indicator and both are OK. Have done all the on-board diagnostic checks and get O2 sensor air-fuel mixture while driving and while idling codes. Components checks are all good. Can all this be related problem? Any ideas?
