Yes, you must remove the intake plenum to replace the idle control valve. I word of warning to those who haven't removed the plenum before but plan to.

There is an oil drain hose on the bottom of the plenum. If you've had the car for any length of time and have never removed the plenum, this hose may have to be cut off of the barbed fitting to free the plenum.

Usually, the hose is long enough that if you cut it off as close to the dip stick as possible, it will still reach when you put the plenum back on.

It wouldn't hurt to have a length of fuel hose available just in case yours has been removed and cut off a few times by previous owners.

You may want to allow some extra time to clean the oil out of the plenum and throttle bodies.

Also, if you have an inspection light, you can look down into the head and see the back of the intake valves and the machined intake ports (only production car of its time with machined ports and kinda' neat).
