92 Toyota SLE V6 Turbo Fuel Problem

[Chad-92 Camry]

Heres the symptoms. One day the car can run smooth as silk the next day it runs like a piece of *%$# and dump masses of fuel.... No really, it runs very rough and to keep it running at red light have to run RPMs up to about 1500 or so. Took to the doctor but they could not put on the computer due to being a 92. ??? Strange I know but that is what they said. Now I have changed the spark plugs, wires, cap, and rotor button. And it still wants to run like crap and dump masses of fuel. It runs fine at high RPMs but at low RPMs it wants to bog down and smoke (smells like str8 GAS( white color)). during normal take off it chugs and bogs down. Now I have also been told that it could be Coolant temp Sensor and or the Fuel Pressure Regulator. If anyone has any insight on the problem please feel free to let me know. Thanks for any help.....

since you are turbo, you're more of a pioneer. what engine are you using?

i thought white smoke means you are burning oil.

for me, unused fuel that is expelled through the pipes is black.

The smoke disappears very rapidly almost like water vapor but if you stand by the end of the car it is a very strong smell of gas. The engine is a 3VFEZ I think .24 valve DOHC 3.0 liter.

what kind fuel management are you using? did you ask the question at toyotanation? there are some guys over there knows alot of about turbo. good luck.

I think it might be the injector faliure...gave run signal or something. last time i tape A/F sensor to wrong wire (injector), and my car was idling very rich too.
