Well, im definantly running rich still...I was able to ohm up all my injectors except the cold start injector, they were all within spec. Now, my question is where is the temp sensor on the 7mgte? Is it the sensor that is inline with the big coolant hose in the front? There looks like there are three sensors in the water jacket. One on top, the one level to the coolant hose and one underneathe. I ohmed up the middle one and the top and neither were in spec according to the tsrm. I don't know if this is my problem, but my car mildly hesitates upon higher rpm and the loss of power is very evident. I checked the 6th and 1st spark plugs and they were both sooty. I changed the plugs and o2 sensor within the past 700 miles also. What else could this be?

^^ My NA used do die like yours does, since this was beofre I knew anything about Supras, I took it to my mechanic, and he just turned the idle screw a bit, and it improved, but thinking back, it sounds like a vacuum leak...
how old are the vac lines? If they are original stock, then they probably need to be replaced. That is were I would start, also, check all intake hoses for cracks...

This thread will help you out. Nice labelled photo of all the sensors. Have you checked your thermostat? If its stuck the car can run cold and stay in warmup mode indefinitely.

The thermostat is inside the housing with all the sensors. Remove the two bolts and it pulls out. Coolant will need to be drained to replace it.
Well my temp sensor didn't do anything after i replaced it. I guess im just gonna have to do a compression check also, since i have some blowby. I took off the pcv hose and i saw some oil in front of the turbo and some in the accordion hose, now im scared.
