DRIVABILITY PROBLEMS

1998 Toyota Corona

Engine Cooling problem
1998 Toyota Corona 4 cyl Front Wheel Drive Automatic 63000 miles

Once my car engine reaches its operating temperature (generally about 200 degrees F, 95 degrees C) it begins to operate improper, problem with idle speed, and at some times reaches at 2000rpm at idle.
But when I unplug the ECT sensor connector the electrical fans activates. This causes the engine to drive normal again. The problem is that my fans will have to be active at all time.
