#12975 of 18329 Intermittent Hesitation, Stumble or Idle Stall by nuyorkah

This may help some of you, check with your dealer.TSB #03-06-04-057 10/01/2003
Intermittent Hesitation, Stumble or Idle Stall after Soak, Harsh 1-2 Shift, Slipping 1-2 Shift Followed by a Harsh Engagement (Reprogram PCM)
2002-2003 Chevrolet TrailBlazer
2002-2003 GMC Envoy
2002-2003 Oldsmobile Bravada
with 4.2L Engine (VIN S - RPO LL8)
Condition:
Some customers may comment on an intermittent hesitation/stumble or idle stall within minutes of starting after the vehicle has been sitting for several hours. Additionally, some customers with a 2003 model year vehicle may comment on a harsh 1-2 shift or 1-2 slip shift that has a bump feeling when 2nd gear engages.
Cause:
This condition may be caused by the EVAP diagnostic test as it opens the purge valve for a few seconds and then closes it to verify proper emission sensor operation. If the purge canister is saturated, the EVAP system on-board diagnostic test may cause the vehicle to correct for a rich condition from the canister. The vehicle would then become lean when the purge valve closes at the completion of the test. This condition occurs primarily with high RVP fuel and after the vehicle sits for several hours in a warm ambient, above 21°C (70°F). A customer who takes short trips is more likely to experience this condition, as they don't have the drive cycle that would allow the purge canister to fully re-circulate the fuel vapor.

how do you take 4 kids in an Envoy? Or is the oldest over 12yrs? Maybe a little over safety concerned but 12 and under should be in the back seat away from the air bags.We just up graded our 98 Grand Voyager to a Tahoe to haul 3 kids.

#12977 of 18329 Front anti roll bar by dlothes
Oct 09, 2003 (6:14 pm)
I read in Motor Trend or R/T recently that for 04 GM changed to a larger front anti roll bar which helped with the wandering feel at highway speeds.Anyone know if that's all they changed, or wonder if they changed the bushings too. Before we bought the 03 I drove a 04 and it felt better to me at highway speeds.
I'm going to get a price quote to see how much.
Think it would be a easy swap?

#12978 of 18329 New Envoy, exhaust by gam2

I think New Envoy has an extended version. He was talking about getting the V-8........I'm sure the computer will compensate for a new muffler. I doubt you'd reduce backpressure too much however, you'd probably just make it louder. Todays factory exhaust are pretty decent to get maximum performance and efficiency (the tailpipe is 2.75" in dia). Many tests have shown that aftermarket exhaust add very little to modern engines. But if you're after a more agressive sound, go for it.

when incentives will start to show up on the 2004 Triplets? I actually want to know specifically about the Isuzu Ascender, but I assume they would be roughly the same, correct?Jim

What funny is the Isuzu is made on the same assembly line as Trailblazer!!! by UAW workers. I would think they would be the same if not better for the isuzu!#12981 of 18329 Stiffer antiroll bars by spdmtr5

will improve pavement handling but may decrease off road compliance.Rutted and bumpy fire roads are a pleasure in the TB when compared to the ride in my Dodge pickup.#12982 of 18329 Just brought a 2002 trailblazer LTZ... by mskay

Two thoughts here.....I'm real happy with mine, very few problems, love it. Some have had lots of problems and got rid of their tb, hopefully you don't have one of those! Seems to me that a lot of the problems with the triplets have been with the more advanced features such as climate control and auto mirrors, things my '02 LS doesn't have, less to go wrong, I guess. my .02...tim#12984 of 18329 mskay by sildog

I assume you bought used? Don't be discouraged by what you read here! By nature, the most vocal are the folks who have the most trouble. I have had my 02 for over two years and 46K. While my experience has not been trouble free, I really like the machine. Remember the silent majority! I know three other people with triplets and they have had no trouble at all and totally love their rides. One guy I know loved his so much but wanted the long, so he traded one in for another and both of his were trouble free. You could always pay $20 for a CARFAX report to see if yours has been back to the dealer a lot or not. (I assume CARFAX gets dealer reports?) Then what do you do? If it has been back a lot, then maybe it is good-the previous owner got all the stuff fixed for you! So far, all I have gotten fixed were one timers that seemed to be fixed for good.To POST a message, please
