    Air ride compressor runs, no inflation?

    Hi all, This literally just occurred. Came outside to find my Envoy XL, 5.3 on the rear bump stops. Normally the rear air ride has been functioning great. When I stsrt it, the compressor runs but bags do not inflate. I have tried standing on the bumper to coax it, but no luck. Any suggestions...

    AC Compressor clutch?

    Hi all, I think the clutch on my AC compressor has gone. It was slowly rotating, producing some cold air, then would blow the #30 fuse under the hood. Each time I replaced the fuse, it would blow. Thinking the clutch is gone. Has anyone had success in replacing the clutch only? Recommended...

    TBSS Wheels are on!

    Thanks! They're 255/55. I might need to drop the rear air bags slightly when I tow our trailer, but that's a little ways off so far. Threw the speedo off by about 3km but I am ok with it. Cheers! Adam

    How to release air from rear air bags?

    The OD of the TBSS wheel measures 2" greater which I calculated will affect hitch height by 1". The hitch was a little high before so I am thinking another 1" will do it. Note: The hitch cant be adjusted in height, it's a weight distribution hitch already set to lowest position. Cheers!

    How to release air from rear air bags?

    Hi all, 2003 Envoy 5.3 XL here. I would like to drop my rear air suspension by 2". I read it's easy to do by pulling the fuse so it learns the new height, however you need to release the air first. Anyone with experience with this? I do not wish to replace the air, it works perfectly (at the...

    TBSS Wheels on my Envoy

    Hi, This might have been asked many times but I failed to see anything in Search. In the spring I will need new tires for my 2003 Envoy XL with 5.3. I have found a good price for TBSS wheels. Will I have any issues? Rubbing? Speedo? My vehicle sits at factory height with functional air...

    Periodic rough idle, codes within thread. Plz help!

    Might have it solved! Replaced the other o2 sensor and put in a new fuel filter, and had the oil pressure switch replaced (unrelated but nice to have the gauge working) Over the past few days it has been running well, fingers crossed!

    Periodic rough idle, codes within thread. Plz help!

    These are great videos, thanks very much. I am leaning towards intake gaskets as my problems do seem more prevalent when the engine is cold. My drive to work is very short so it doesn't get much chance during the week to heat up properly, unless there is a long lineup at the Drive Thru, lol...

    Periodic rough idle, codes within thread. Plz help!

    So here is an update: Bank 1 sensor 1 has been replaced and I am no longer getting the P1133. What I am getting now us PO300 and a PO174. It still occasionally acts up, but it comes and goes, strange. I gave it a Seafoam can in the tank and have been running higher octane gas. I also changed the...
