Under the hood on the passenger side. It sits on top of the wheel well directly under the side mounted coolant reservoir which has to be lifted out of the way to reach it.

the ecm for a 1998 grand prix is in the air intake box. it is pretty simple to get out, take a look if you need more help e-mail me

Under hood, passenger side, and under coolant reservoir

Idle is controlled by the ECM (computer). Not adjustable. check sensors

Ecm is located behind instrument panel. Havent got it out yet looks to be fun

If they are the same year/engine/transmission it should be the same ECM.

there is a rev limit setting in the ecm so you dont over rev the motor

The governor isn't a physical object... it's a line of programming in the engine ECM. You'd need to have a diagnostic computer with the appropriate software pluggd into it and adjust it from there.

left side near the steering column

It is in the ECM and not removable. You'll need to buy a performance chip.

unplug the 12v batt for at least 30's

Under the dash, left side you will have to remove the close out panel.

No, it is hardwired into the ecm and the rest of the car.

my car is doing the same this right now have you checked your ecm(Engine Control Computer) tha is most likely your problem

your ecm could be going bad or need to be reprogramed when you turn your key on the ecm resets

Under the glove box, there is a panel, I think you need a 7mm socket. Remove the panel and there it is.
