    Anyone know if CV joints and boots are covered under GM's extended warranty. Mine are starting to leak at 39,000 miles! Doh!

    Also, anyone look under their trucks recently. my '03 is really rusty all over. I thought these frame had special paint applied to them??

    Hi here is the update on my 03 Envoy stalling. They had the data recorder on it all it way tell them that it was stalling 3 min 45 second to 4 min into the first drive after setting and the fuel was going very rich before it stalled. It was at the dealer for a week dealer and the gm tech could not figure it out and it would not stall for them they call be and ask me to come in and road tested with their tech so I did 3 min 45 sec in to the drive it stalled and the tech hit the data recorder again. So it was at the dealer for a couple more days and the call me they turned the information from the data recorder over to a different GM tech and he can up with the purge value for the charcoal canister system was stay open the fumes was making it very rich and the computer was try to over come the rich my lean it out and it would stalling. So it has been two week and know stalling but ever seens we pickup the Envoy it want to vibrate at low rpm wearse if you have the A/C on like when we back up out of our driveway with the wheels turn a little it vibrate the hole time also some time when you are try to take off from a stop it want to hesitates when you give it gas. Took it back to the dealer they say they feel the vibration that it is normal and I tell them that it never done it before and the said they don't feel the hesitation.
    I am still work with the lawyer on mine.

    I have noticed my 2002 TB almost stalling quite a few times. If I catch a certain light red which is about 3.5 min from startup in the morning, while I am sitting waiting for the light to change, I will feel it stumble a little at that time if I am stopped, and sometimes the RPM will drop down to 200-300 and catch itself. If I make it through that light on green I would never know that anything is happening. A month ago with its first tank of this new gas with ethanol we have here now, it DID indeed stall out, actually quit running for the first time, while I was sitting stopped, exactly 3:50 after startup into the drive.

    I keep a CarChip EX plugged into the OBD2 port and two of the parameters it records are Fuel Trim and RPM. At the exact point the RPM drops, the Fuel Trim goes way lean trying to compensate for the canister being purged. I figured this out a couple of years ago, got it reprogrammed once, it ran better but did not fix the almost stall situation. Since it had never died before I did not pursue it further, and now that it's well out of warranty it has stalled for the first time.

    As to the vibration at idle, sounds like they reprogrammed it to lower the idle RPM a little. My idle speed will vary a little bit and when it's on the high side around 630 I can barely feel the engine running. 10-20 RPM slower and it vibrates excessively, to the point the steering wheel will resonate with it and will be visibly vibrating vertically!

    Another thing to try is to clean the throttle body. I've not had to, but have read of several that cleaning helped idle problems. Apparently the throttle body can get oil and dirt build up around where the butterfly rests at idle. Result can disturb the air flow, and cause the throttle movement to get sticky when it has to make small corrections to keep idle speed constant.

    Hi thank for the info the stall sound the same it stall more after filling the Envoy some time after fueling it would take two to three time cracking to get it to start or if it start the first time it would run very rough and then clear up. Know more problem with fuel or stalling in two week sense the replace the purge solenoid only the vibration I will ask them about the idle. They clean my throttle body, injector and top end two different time when they were try to find the stall.
    Thanks for the help will let you know after I ask them about the idle.

    Anyone use I-Pass (or similar) on their Envoy for auotmatic tolls? Does the compass interfere with the
    operation? I'm tired of getting raped on the Illinois Tollway.

    I use something called "Fasttrack" to go over the Bay Bridge (San Francisco). It's a transponder. Didn't want to put in by the mirror - so I keep it in the side pocket and hold it up to the sunroof when I go through. I used to think that the GPS antenna was in the mirror - but later figured out that it was located in the A Pillar - so my concerns are probably unfounded. It shouldn't mess up the compass - because a transponder doesn't do anything until interrogated. Likewise, the compass is a passive device and shouldn't effect the transponder...

    Thanks wpkelleysr for the link that picture is fantastic. I was looking much lower and to the left and I couldn't see it.

    I can't get my hand in there to replace the sensor. I suppose I have to unscrew the front panel (the smaller bolt "northwest" of the sensor in the picture).
  • tblazedtblazed Posts: 945
    Thanks should also go out to N7DON who supplied that picture. (I am the one hosting the picture - "epadget" = tblazed.) Glad to know wpkelleysr remembered it! When that link got posted the other day, I realized that old picture out of the GM manual was in error so I uploaded the actual picture of the sensor connector on N7DON's Envoy. Should eliminate any question about where that pesky sensor is located!

    Tblazed - the new picture's great. Thanks for the original some time ago - I never would have found that $@#*& thing without it.

    rj123456: Once I had the grill off, I didn't really have to remove anything else. I wiggled the sensor housing out of the frame, then removed the smaller sensor, replaced it with the new sensor, then stuffed the housing back like it was. Works great now.

    Ok thanks everyone!

    Waiting on my package (including the sensor) from gmpartsdirect. It says "Shipped DHL" but the tracking # shows Fedex picked it up on 5/22 (and no status after that, weird?).

    What? You don't like paying double for tolls? :D

    I had I-Pass in my Envoy. Didn't interfere with anything. Haven't gotten up the nerve to glue it to the window of my TB SS yet. I'm not on the tollway very often.

    Just leased a brand new 06 envoy..after driving for 2 days i've noticed the brakes squeaking very loudly right before the truck stops and then again right after I press the gas. This happens for about 5 or so seconds each time i break and press the gas, then it stops. Sometimes this squeaking continues when i am driving as well. Any one have any ideas as to why this is happening? Thank you.
  • tblazedtblazed Posts: 945
    Since it was new when you took delivery, maybe it had been sitting in inventory a few months and had rust on the rotors, then driving it a couple of days loaded up the pads with the rust and now they squeal. That'd be my guess. Might need to take it back have them clean up the rotors and replace the pads.
  • gam2gam2 Posts: 306
    Yeah, isn't it great when you have to pay double tolls if you use the "Official" currency of the USA? HA! I-Pass worked good though. No problems.

    I changed my '03 Tblzr transmission fluid at 60k miles. I am currently at 83k and expect to drive about 1300 miles before a one-way trip down south (totalling about 960 miles) within the next 3 weeks. The dealer is recommending that we change the transmission filter in addition with the flush. Should we change the filter along with the flush or should we just get the flush? I need your opinion.
    THANK YOU

    Anyone know how to open a jammed 2003 Envoy hood. Hood opened fine yesterday, now it's jammed stuck after a 200 mile drive. The release cable appears to be intact and this is the fist time it's happened since new. I tried pushing down on the hood (gently) tapping it, but it's really stuck. No obvious way to release it at the catch...

    I would not get a power flush of any auto tranny. You stand a chance of flush junk into your valve body. SNOKING
  • gam2gam2 Posts: 306
    Why are you going to flush it again after only 23K miles?
    It should be fine for a short trip like that. You not towing anything are you?
  • wpkelleysrwpkelleysr Posts: 51
    Seems a little premature. You should be fine....
