Thanks to this forum I corrected the following problems in my 03 Envoy. Loose steering and bad metallic grinding noise when shifting from park to reverse were caused by a bad half shaft. This was done twice, once in 04 than again in 05. In 04 it had to be special ordered. It took three weeks to get. In 05 it was in stock which made me suspicious that they had a stockpile of half shafts readily available. I've read on this forum that this is a redesigned part. Problem two was the air conditioning blowing hot air especially while stopped. After several visits to the dealership, the AC cycling switch was replaced. It did not solve the problem. After my regular warranty ran out, I was able to use the extended warranty I purchased at an independent car repair shop I've used. From this site I learned about the redesigned cooling fan clutch. It was replaced and AC works better now than day one. Also had the right sway bar link (read about this in this forum) replaced and it elimnated an annoying squeaking noise which happened over bumps and left turns. I don't know which makes me happier, having my car finally fixed after three long years or knowing I never have to go back to the horrible GM service department.
#17714 of 18329 acceleration hesitation
Mar 31, 2006 (10:49 am)
I recently experienced the stalling and erratic idling of my 2002 LS TB, took it to the dealer about a month ago for two days and they reprogrammed the computer for free according to a software recall. I also had the air and fuel filter changed, fuel pump checked.
The truck would (intermittently) rev up and down while idling causing the engine to eventually stall. When you tried to accelerate while this was happening, the tach would go up, but the truck would shutter and spit and severely hesitate. Since having it fixed, the idling problem has not occurred, however the SES light has been on and I'm experiencing some major hesitation in accelerating while going 50-60 MPH. When you step on the gas to go a little faster like going uphill etc, the truck actually goes slower for a few seconds as if it was not getting any gas. Then it seems to kick in and take off, only to do it again when you step on the gas the next time.
This is very intermittent, but seems to happen more frequently within the first 5 or 10 miles of a trip.
Can anyone help out? I see a lot about the TSB 1652870 and will have the dealer look into this, but as you know, everything gets expensive especially when I am still paying on the 02 and have 85K miles!!
PS, I also have experienced other issues which seem to be prevalent on this board, anyone please feel free to email me and ask if I can help, hopefully I can!

Well I left mine at the dealer for a week when I was on vacation of couse it would not stall for them. Try to tell them about so of the think you guy said to check they did not want to know they just want me to take the Envoy and let them know If it stall again I told them I would only take it if the put one of those Data recorder on the Envoy the didn't finally they did so now the data recorder is on but I think it not work right becauce say when you start engine hit switch and red light should come on and when you when it stall you should hit the button again and the light should start blink show that it is recordering, it just blink with engine running or not so I will proably have a dead battery in the morning.
I'll let you know what happen Pete

Just wondering if anyone has the V-8 and what kind of HWY mileage you are seeing????
I have an Envoy with the 6 and am going to need to get another vehicle very soon. (I drive tons of hwy miles). I could really use the extra space offered by the Tahoe/Yukon but it looks like I would be getting 18-19 hwy which would cost me an extra thousand dollars per year in fuel (I have done the math), which is not out of the question. I currently get 21-22 mpg am am ok with that. I would like a little extra "grunt" though and the extra torque of the V-8 would give that I think. Question:
If I stick with the Envoy/Trailblazer/Buick/Isuzu/etc bodystyle, what are my options in getting one with a V-8??? I want to go used and try to find something with 10-20k miles on it. I also do not care too much for the "extended" version of envoy so would like to stay short. If I am going to get an XL I would get a Tahoe. I have flipped back and forth, I dont know what to do.....

In the short wheel based verson, you can get the GMC Envoy Denali and the Buick Rainer with V-8's. I am sure you can get 20mpg on the hwy. You cannot get the V-8 in the short wheel TB unless you get the SS (corvette engine). I agree, I do not like the extended verson of the Envoy or Trailblazer- it is too much like a tunnel and makes me feel claustrophobic, not to mention the handling is not as good as the short wheeled. I think the extended version "porposes" down the highway with the way too soft suspension. That motion sickness will make anyone sick who is riding in the back. If I were in the market I would get a 2006 Tahoe with the 3:23 rear end and 5.3 V-8. The 4.8 V-8 option in the Tahoe is a little too small for that size of vehicle. Just my opinon.

gmfan is correct. The TB only has the V-8 if you get the extended version or the SS. I have the extended version and like the extra power. I also would recommend the 5.3 V-8 over the 4.8. IMO, the 5.3 V-8 is the best engine Chevrolet makes. I have plenty of power on my TB and I don't think my suspension is to soft. The extended TB and Envoy have been discontinued and the new Thaoe looks a lot like the Equinox but big. I think it is quite attractive. Best of luck.

I know of at least one 2006 short wheelbase Trailblazer LT with the 5.3 V8. I think the V8 became an option on the short TB in 2006.
