I don't think it will cost you anything! All you need to do is lighten up on the gas pedal when you're pressing the clutch pedal.

The engine is doing the revving on its own every time I push in on the clutch. It looks like the clutch has gone out. It has 120k miles on it. Is that the normal life for a clutch?

Clutches, like brakes and tires are a wear item... Much of the life is going to depend on how they are used (or abused). Personnally, I think 120k is pretty decent distance on a clutch. As for the revving, check the throttle cable. Sounds like it's sticking either bunched up floor mat, or broken spring at the throttle body.

Clean the throttle body with some carb cleaner and a toothbrush - probably gummed up on the butterfly or throttle valve. See if thst does it first. Check the vac lines too.

Excuse my ignorance, where is the throttle body located and is it something simple enough for me to handle on my own?

Its the thing that the air goes thru (like the old carb) but no fuel - yours is injected so fuel cleaner never goes thru it. Remove the tall screw on the back of the air housing center of engine, remove the pipe at the rubber grommet, tilt the black plastic housing up to unclip it on the front edge and lift off. Now you see the throttle body and with eye protection on you spray carb cleaner in and hold the throttle open and use a toothbrush to clean it so all black gunk is gone. Replace all things and start - may shake for a few seconds till the cleaner burns off.

Loss of throttle at 90 mph / 150 km

North bound from Niagara Falls NY to Toronto today. Lost all throttle at 90 mph. The truck remained on and everthing was fine however when I hit 90 mph it felt as if I'd hit a govenor. As the truck slowed below the speed the accelerator seemed to kick in again. I tried after a while to reach 90 mph again and at the same speed and this event was repeated. I purchased this 2002 ZR2 this year from the original owner. I spoke w/ her today and she stated she seldom drove over 70 - 80 mph and never experienced what I described. Wondering if anyone is aware of this.

Computer programmed at approx 93 to limit you - have to buy an aftermarket programmer to alter. With a ZR2 4wd I'd avoid those speeds from the standpoint of your drivetrain and transfer case - lots of Extremes get altered but 2wd.

It has a speed limiter as do all newer vehicles (at least GM). Newer vehicles also have "little black boxes" similar to that of an aircraft that record data, such as rate of speed and law enforcement can (and have)extract that information should the need arise, from say an accident.
