It sounds like your idle control valve is sticking. The video shows you where they are located on a 97 Buick but it is the same engine.
This video shows you how to replace them.

It is a 24 year old vehicle (made in 94), it probably needs to retire :>)

Take it to a transmission specialist rather than a normal garage, as it sounds like a sensor problem. It may also be rubber mountings that have perished, and the engine and transmission are only partially mounted to the chassis.

The coolant temperature sensor is a thermistor mounted in the engine coolant stream. A thermistor is an electrical device that varies its resistance in relation to changes in temperature.

For 2.5L engines, the coolant temperature sensor is located on the left side of the cylinder head.

For MFI engines, the coolant temperature sensor is located on the intake manifold water jacket or near (or on) the thermostat housing.

I would suggest having the vehicle put on a scanner and monitor the operating parameters of the sensor for heater signal operation and sensor performance. You may not have overlooked anything. However, without knowing what the sensor is actually doing nand reading, you will be chasing your tail

Find the radio station you would like to store. Then press and hold down the button you wish to assign to that station until you hear a BEEP. That station will then be stored to that button.

Check the battery,have a load test done on the battery,now,it could be that the battery terminals,and battery cable ends are corroded,clean them really good,shining clean,this makes a big difference.Good idea to have the alternator checked also,while on the vehicle running,with the head lights on,and high blower motor,it should read at the battery,13.65 volts,to 14.25 volts.

If you follow up the brake pedal towards the steering column, you will see the switch.The switch can be at the front of the pedal or at the back of the pedal. It's not a difficult replacement, it's just hard to lay on your back in that small space and do the job. The part costs about $10.00. The question I have is why are you looking to replace? The faults are usually brake lights stay on which will kill your battery , or switch is bad and brake lights don't come on when pedal is depressed. I would first check for blown fuses, and blown bulbs. If you need any additional help please get back to me. GOOD LUCK FREIND.

it is better to gut out the valve and reinstall it but it should come out with the first exhaust pipe.

i had the same problem had to replace the turn signal switch....GM for some reason wired the brake lights through the turn signal switch. to check if this is the case with yours. put some pressure on the turn signal lever as if you were going to turn on your brights and press your brake pedal and see if the lights work at that point that is how i found mine. hope this helps. if indeed they work with pressure on the turn signal lever. the new switch cost me $60 at autozone and that is with the steering wheel radio controls, make sure you get the proper switch should be part# sw771 if you have the radio controls on steering wheel and you will need a steering wheel puller and lock plate compressing tool.

You have a rod that goes from your door handle to the latch opener, inside the door panel. It has probably came off. You will need to take off your door panel to get to it. There are just a few screws on the corner of the panel. Remove them and then you will need to move the plastic and foam in the inside of the door. After this, you should be able to get to the rod. Hope this helps you.
