Never heard of the servo failing. I was skeptical when they first announced this for the Vette, but I've heard of no problems.

I wish I had a cable, I can tell a slight delay in the throttle response in a cable and servo, and even between servos. My truck is fly by wire as well and it doesnt have as much of a delay.
I'm not worried about it failing tho

I'm not sure how you can feel the difference, but, like most things on the C5, couldn't you have it electronically adjusted?

Fly-By-Wire.
1) I had a 2000 SS Camaro and the cable stuck on me three times at WOT. Scared the **** out of me the first time.
2) FBW idle quality can be adjusted easier for large cams. Cable TB usually require the 1/4" drill bit solution.

Hey, do you want Mr. Goodwrench to begin looking like Mr. Maytag. If you do convince GM to make your recommended change, see if you can them them to do the following:
1. eliminate inherent alternator problems between 1982 and 1997.
2. eliminate rear brake problems on 90+ GM models.
3. eliminate window problems on most GMs in past 10 years.
4. eliminate a/c problems (doors under right side of dash on late model cadillac.
5. eliminate major oil leak problems on northstar between 93 and 99.
6. eliminate stripped head bolts on northstar between 93 and 99.
You might have a really neat idea.

I only had one issue with a servo, but that was on an LS2 TB, and a very early harness. We had to de-engineer it to get it to work
Off topic but the LS2 TB fealt very stiff and spungy off idle. I went that way to get my wife to drive the car more, but I hated it, and went to a NW 90mm TB... Thanks!Dave

Fly by wire all the way! Couldn't care less if it has a cable (old school)! It is new school time!
Most of all the car manufaturers are using the fly by wire set-up! Works great!
Thanks,Matt

The throttle is just but another one of the many items that goes into the PCM that controls engine performance. There are certain conditions (don't know exactly all the things) that WOT at the foot, may not translate to WOT at the engine due to air temps, spark advance, Outside air temp/ Fuel air mix as detected by O2 sensors, etc, etc.

Actually, the first drive by wire I had was in a Cadillac - Eldorado ETC,300HP Northstar.
When I got the car, I knew it had the best throttle response I had ever driven. Later, I found out it was drive by wire.
My current DD, Acura RL, also has it. Now the 'vette. I think it is much superior to cable. No pressure variation, perfectly linear. I have no interest in going back to cable or do have any fear of it failing.

Not one problem with my car's fly-by-wire throttle control. Really don't miss the cable at all.

I just sold my 97 pearl crimson (candy apple red) Sedan de Ville. 27k miles on it. Most beautiful car in country. I never had any problems with mine, but I know quite a few caddy mechanics. I will miss that car, but it is now 10 years old. Couple that bought it did not even take it for a test drive. That is the second time that I have sold a car without a test drive.
I still like GM products, considering the fact that Ford trannies go out at 100k. Also, you have to take the entire front cap off of a Taurus to get at a/c and/or radiator.
Best kept secret in America is the Buick. Centuries are great for kids. LeSabres and Centuries get 200k miles as long as you maintain them.
