TSB from GM specifically states that the dealer is not to try and fix, adjust or clean the throttle body and must replace. Gee, did they spend anytime looking this one up?

Increased Accelerator Pedal Effort
(Replace Throttle Body)
1999-20O0 Chevrolet and GMC C/K Pickup Models (Silverado and Sierra) with 4.8 L, 5.3 L or 6.0 L V8 Engine (VINS V, T, U - RPOs LR4, LM7, LQ4)
This bulletin is being revised to add additional part numbers and clarify labor operations. Please discard Corporate Bulletin Number 00-06-04-007
(Section 06- Engine controls).
Some customers may comment on a higher than expected accelerator pedal effort from the idle position.
Condition may be caused by a tight throttle blade in the throttle body bore when in the closed position.
Notice DO NOT adjust the shipping air screw to rotate the throttle body blade away from the throttle body bore. Adjusting the shipping air screw compromises the idle speed control, and may lead to other driveability concerns. Adjusting the shipping air screw may lead to reduced idle Air Control valve durability.
1. Verify the cause for this condition is not a damaged or binding throttle cable.
2. Remove the throttle body (3) from the engine and inspect the 4 digit Julian date code (2) stamped on the bottom edge of the mounting flange. The Julian date code is stamped on the lower edge of the mounting flange, next to the gasket edge,on the side of the throttle position sensor. The stamped 5 digit code (1) is the last 5 digits of the Throttle Body Assembly Part Number. See Figure 1 - Throttle Body Date Code Identification.
3. If the Date Code is 2979, or earlier:
^ Replace the Throttle Body Assembly using appropriate Service Manual procedure.
^ DO NOT clean the Throttle Body Assembly.
^ DO NOT attempt to adjust Throttle Assemblies.
Parts are currently available from GMSPO.

Don't go "pushing" vans around with your grill guard. It'll just end up twisting your bumper, or pushing the guard back into the grill. They look tough, but they do more damage to the front in an accident than not having one. Yoos the tow huke Luke! Force be with you!

This darn thing is bolted up pretty good. Its actually classified as a push bar. I know if im going 70 mph it wont protect the front end but for pushing things at slow speeds and not ramming into them it seems like itll work fine. I think ill test it out on my dads truck one of these days.
It was so funny to watch this guy sit and spin his tires for 30 min. Felt bad for the guy but i wasnt going in the mud to push him out. I really do wish i had my truck.
(quad i do have a tow strap in my truck under the back seat for emergency uses)
Funny thing i also seen by my uncles house. Me and my gf are going into the house after we went shopping. New reg cab 4x4 silverado goes by. As it goes by you wouldnt believe it but it had GMC rims on it. I was like what a goof gmc rims on a chevy truck. My gf was like "you are the only person who would notice something like that"

Doesn't matter how it's classified. Look at what, and where, it's bolted to for the answer.
I know you don't believe anything I tell you at first Ryan. Just harken back to what quad told you in the beginning, like on dad's S10...said "take it to dealer." What did you do? 2 sensors, one cat and hours of frustration later? Shoulda listened to quad!!!
Jun 03, 2001 (12:21 am)
it cost hmmm $40 for one sensor and $275 for the exhaust/cat.
Dealership would have been ??? outrageous i can tell you that. They probably would have kept it 2-3 days also.
It really wasnt hours of frustraion. Total number of hrs it took to diagnose was id probably say 2.5. Hr here hr there after work. This wk it is getting new shocks. Last wk it got new trans fluid and filter. Itll be like a new truck soon.
If its out of warranty screw the dealerships. Work on it yourself.

#3373 of 6769 Let the boy do what he has to do....
Jun 03, 2001 (6:32 am)
front end of the truck is all plastic anyway and the stock plastic trim in the grill would look better if it wasn't there so I vote for using the grill guard for pushing whatever he wants to push....hehe
Later you can tell him I told you so...and I'll be a witness.
Jun 03, 2001 (6:35 am)
...you'd better look underneith to be sure of the gender of your truck!
....as for mean looking girls....well....I'll just leave that one alone....

don't listen to what anyone says about pushing another vehicle with your truck. Hey man, you've got a Mighty Moe grill guard bolted up to that bad boy, so it's definately a manly truck to be sure. just ram the hell out of that van man. remember the commercial where a guy in a chevy Suv pulls up to a semi that's stranded? if he can pull a semi, then you can sure push one right?
don't worry bout no plastic parts neither, that's what super glue is for.
good luck on this one now!
#3376 of 6769 Extended Warranty or Not
Jun 03, 2001 (7:14 am)
I just bought a 98 Silverado with 2 weeks and 200 miles left on the Factory Warranty. Thinking about extended warranty?? Checked with dealer only warranty work performed was a master cylinder and battery. If and where is the big question. Fuel pump is making noise and the local dealer was going to replace under warranty. When I took it in they didn't have time. Closest dealer is 30 miles, not very good service, big city is 85 miles. I am capable of doing the work I just don't have all the fancy tools. Thanks in advance for any input.
