What component controls high idle on cold startup on a 2000 chevy blazer?

The engine computer uses the idle air control valve in all temp ranges to control idle speed. The throttle plate could also be sticking open.

Run away vehicle-99 chevy blazer wants to accelerate to 1500 rpm,braking will bring idle back down. What's problem?

In most cases problems with idle speed involve the idle air control valve or a dirty throttle body. The computer controls idle speed by how much air is allowed into the intake thru the control valve.
If the throttle is not sticking, I would check the valve and the bore of the throttle body.
You could also have a vac leak but that would usually be a constant problem.

What causes a 1995 chevy blazer 4x4 4.3 die when u come to a dead stop ?

Try doing the following.

Engine stalling issue at low speeds

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

Feel the hoses going to heater core, one should be hot and the other warm. If one is cold or both are then heater core is clogged. Make sure heater control valve works and as vacuum to it and or the cable is free.

Start by flushing your coolant system and replacing your thermostat. You may later find that you have a clogged heater core.

My 1988 f150 does the same thing..idling problem!

Having the proper thermostat in fuel injected vehicles is very important.They have a engine coolant sensor to tell the computer the temp of the coolant. If the engine is running too cold,(or cold all the time), the computer is going to tell the idle motor to raise the idle and to give it more fuel, which can damage the cat converter. These vehicles need a 192-195 degree thermostat. Also check the TP sensor (throttle position sensor for proper voltage) the green wire should read .7 to 1.00 volts.

Changed radiator and thermostat in 1985 chevy blazer it ran at 210 degrees, then I drove up and down a hilly terrain and needle approached red zone inside gage, what's wrong?

195 degrees is the hottest thermostat you can buy, and the warmest your Blazer should get to.

Did you bleed the air out after installing the thermostat? Trapped air will not allow the coolant to do it's job.

2001 Chevy Blazer has check engine light on and hard to start.

Try IAC the idle air control because its what compensates a rich or lean mixture. There is another sensor called ECT sensor which reads off the tempature of the coolant
