Check that you car is not climate control as this will turn on the ac compressor as well as the heater to give you controlled temp in the car. If that is the case the idle speed sensor and ambient sensors in the cpu may not be doing the job as the engine speed should increase to compensate for the extra load of the compressor. Have a fault code reading done.

What is causing it to cut out?


Could be just a dirty idle air control motor, which can be cleaned sometimes. Your shop manual should tell how.

My 98 pontiac grandam bogs out and tries to die


the idle up solenoid may be disconnected it is usually a vaccume hose that detects extra load when ac is on and slightly raises idle . however the over heating issue is a concern . check that the radiator has coolant and all air is blead from the coolant system, check that the electric cooling fans are operational and they should come on regardless of the eng temp if ac is on. if fans are not working check coolant fan fuses

My envoy idles up and down when i turn my defroster is on


When you place your controls on defrost it turns your air conditioner on - depending what the heat level is set on the air conditioner will cycle on and off to regulate temp. Anytime the A/C runs the idle sensor will bring the idle up

I have a 97 ranger(2.3)When I use the heat or defrost the engine starts revving up high.It goes back to normal as soon as I turn off the heat.


the engine computer is rasing the idle speed when ever the a/c compressor starts to operate. So it is adding too much air and therefore fuel. The duty cycle of the fast idle solenoid or compensator is off. Check the idle air controls.

When i turn on the heater it seems to affect the transmission.the jeep seems to bog down when accelerating but as soon as i turn off the heat it runs fine.


well as far as the bog down issue it will bog down a bit in defrost mode because it uses the air conditioner compressor to control humidity does it do the same thing when u use the air conditioner

but if u are putting on the vents it shouldnt use the compressor and if it is then i would that the selector switch is malfunctioning

Per your description, it sounds like you have a vacuum leak.
Check all vacuum hoses at the engine, make sure no hoses are disconnected, cracked or damaged.
Disconnect each hose at the source on the engine and see if the engine idle stabilizes.
Let me know what you find and we can go from there.
Regards.
