I do believe your pcm box on most Pontiac , chev ,&gmc,s are located on the fire wall inside car behind the glove box. Just remove your glove box door & glove box liner it should only be 4-6 screws to remove both once removed you will be able to see the pcm box. It is a silvery tin box with a wiring harness running into it , but before you attempt to remove it or unplug the wiring harness disconnect your battery

It is the computer.
According to my Hayes repair manual the PCM is located inside the right front fender.
PCM = Power Control Module. It is the car's main computer/brain. Also can be referred to as the ECU or ECM.
Behind the glove box.
The PCM is located in the right corner of the engine compartment under the air cleaner assembly and bolted to the chassis.
It is under the air box. First remove the air box, then move the coolant reservoir to the left, remove the brace, then you have access to the cover of the pcm.
Shinny metal box behind the glove box. Glove box door need only to remove to gain access to PCM.
If you mean the pcm, then its inside the air filter box on the bottom
It is called a PCM. and it is located in the bottom of the air filter box.
Do you mean PCM? if so it is inside the air filter box on the bottom.
You don't- it's controlled by the PCM. If is has a 2.5 engine you cann't adjust the timing
it is located under the passenger side dash. it has a red and white and blue connector. first remove the plastic hush pad and it is visable. the squeeze each tab on each connector and slide the pcm out.
