    Battery not charging message but it is sometimes

    The old negative cable had a ton of corrosion under it and I replaced that over a year ago with a new one. First time I’ve seen the battery not charging message. I’ll take another look at the positive cable and report back.

    Battery not charging message but it is sometimes

    @EfiniMotorsport Did you ever get this resolved? My 03 burb just gave me the battery not charging on startup today but went away after a minute of driving. All my grounds are clean, new negative cable. Positive cable is clean. If it happens again, guess I’ll change the alternator? It may be...

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

    Holy crap that fuel injector cleaning service really helps! We got 22 miles to the gallon down to Phoenix and back up to mayor / Arcosanti. 15mpg on the climb from Arcosanti to NAZ. Best I could ever get before was 18 - 19 down and 13-14 up. Fuel trims are still negative at idle but while...

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

    I’ve only put on 100 miles since injectors were cleaned and LTFT are still -7 to - 12 at idle but during driving my STFT are now adding fuel occasionally along with the LTFT. This is a change for the good as before injector cleaning it was almost always removing fuel at idle and driving. I’ll...

    I don’t have a nice enough scanner to reset LTFT. I disconnect battery for a few days which I thought reset the LTFT? If not hopefully it will get better after 100 miles or so.

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

    Received my cleaned fuel injectors back with new upper and lower O-rings although I had to replace the lowers with the originals as the O-ring they included were just a little bit too big and I couldn’t get the injector all the way in the intake. The place I used only charges $9-$10 per...

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

    Sending off all 8 injectiors to this cleaning service. Comes out to about $10 per injector. They don’t give flow rates or anything special but have good reviews and I’ll update if my LTFT improve from the -10 through -3 I’m currently seeing once they are clean and reinstalled...

    Shorty headers worth it for 5.3?

    Sounds like I should just stick to stock manifolds when mine fail. Thanks for the responses and video link!

    Shorty headers worth it for 5.3?

    I have a blackbear tuned 2003 suburban z71 5.3 4x4 3:73. I have a afe cold air intake and replaced stock muffler with a magnaflow. Stock cats. I hear a tick on cold startup which mostly goes away when at operating temp but I’ve already replaced manifold gaskets and all broken bolts except the...

    Cold Air Intake for the most power??

    i purchased one used from a different forum member and the other on Amazon but a return sold by Amazon warehouse. Both were a good discount vs buying new and paying retail so check marketplace, etc.

    Cold Air Intake for the most power??

    I have 2 afe CAI. Besides looking cool, cleaning up the engine bay and more intake noise I can’t tell a power difference but blackbear did a test showing some power gains. https://www.blackbearperformance.com/blogs/articles/black-bear-performance-cold-air-intake-test-results Installed on my...

    Those Who Moved From an '07-14 to '15+ generation... How Was It?

    Thanks! The 97 k1500 is the reason I’m a GM truck and SUV guy. Those quick disconnects suck! Haha I have videos of the fleet on my YouTube channel https://youtube.com/@doctube2020?si=lqoSEvBgZ5y1WSbQ

    Those Who Moved From an '07-14 to '15+ generation... How Was It?

    I might be a little bit off-topic below since I am a generation or two older, but to answer the op question I would totally recommend a K2XX over a GMT900. Mostly because of the more updated powertrain and interior quality improvements. I’ve read in a few different places by a 2016 and up SUV as...

    Negative long term fuel trims

    @EdMay Start with the simple things: Check your air intake, rubber boots, and plastic hose for any cracks allowing a vacuum leak. Check around intake for vacuum leaks. are your catalytic converters good? I’d suggest replacing the downstream sensors as well. When did this problem start after...

    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...
