    Long term and short term fuel trims intake leak, low idle, improving fuel mileage. Mpg

    Update: I cleaned my oem Delphi MAF with a q-tip soaked in crc maf cleaner. I gently rubbed the Q-tip on the intake side of each wire, and there was still a little fuzz and dirt built-up that I was able to remove since when you just spray the wires, you can only spray from the downflow side, not...

    My current fuel trims - idle, 2000rpm, 3000rpm all no load

    Here’s a thread on my fuel trims. My 03 burb 5.3 LM7 (non flex fuel) likes to take away fuel aka negative long term fuel trims. Helpful YouTube videos on page 1. My fuel trims at various rpm page 2. I’ve gotten 16 - 17 mpg driving 65 mph on a 200 mile trip. So I’m calling it good even though...

    Escalade cluster and other goodies for sale

    I reached out to blackbear, and since I originally did the traditional tune less than a year ago, they offered a discount on the auto cal tune. I really just needed a way to adjust the tire size. But I guess the auto cal tune is slightly better than a traditional tune? Not sure if I want to pay...

    New Here w/ an '01 Tahoe 5.3L

    Welcome! Good looking Tahoe. Make sure you test the new knock sensors before installing. I bought several acdelco knock sensors that were dead out of the box. Ended up buying delphi sensors and those were good. Several YouTube videos on how to test with voltmeter. Both sensors should produce a...

    04 Suburban Cluster Issue

    I had a similar issue in my 03 burb where the fuel gauge would read E and low fuel on the DIC but if you would rock the burb side to side it would read fuel level normally. I also had a code for P0463 fuel level sensor circuit high. This is a common problem on earlier years where the fuel...

    Truck smells like farts in the morning

    I’ve heard some YouTube reviews complain that aging GM interiors, especially ones with the fake leather smell like sweat, wet dog, sour smells as they age. I have a 2003 suburban with the fake leather seats and even after shampooing the carpet twice I still have the damp, wet dog sour sweats...

    GMT800 on star temp rear view mirror cold temp malfunction

    Looks like they’re about $30 shipped on eBay. May just go that route instead of driving out to junkyard. First I’ll checkout YouTube repair video and give that a go. I guess 2003 wasn’t the best year for electronics? First my radio had problems in the cold now the mirror Blame lead free soldier!

    01 rear view mirror with compass and temp

    Have you tried swapping in a replacement rear view form a junkyard? That would tell you if it’s your mirror or a connection or module that’s failed.

    Odd Bose radio issues. No sound when cold. Randomly powers off for a few seconds. Occasional theftlock briefly then works fine.

    I am still getting U1000 and U1016 codes even though my sound is now working when cold. Also getting Rear Seat Entertainment comm issues. I get some static squealing noise from the rear speakers when truck is first started so I am going to swap out the RSE control panel with a junkyard spare and...

    Odd Bose radio issues. No sound when cold. Randomly powers off for a few seconds. Occasional theftlock briefly then works fine.

    I thought my no sound when cold issue was the bose amp but turns out it was the radio head unit in the dash. I tested this by bringing the radio in the house overnight while everything else was outside in the cold. Installed warm radio and everything worked fine. You can just swap bose amps...

    Odd Bose radio issues. No sound when cold. Randomly powers off for a few seconds. Occasional theftlock briefly then works fine.

    Is your system Bose? If so, are you still using the BOSE amp or did you bypass it when you went with the aftermarket radio? If you’re still using the BOSE amp (installed under center console) that’s another common failure point.

    update Found another oem GM radio. Same Delphi part number as my current radio. Installed it and of course got the theft lock message. Tried a VCX nano tech2win from eBay and it would not clear the Vin no matter what I tried even rolled back the tech2 software from to version 30 which is...
