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

    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...

    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...

    What did you do to your NBS GMT800 Tahoe/Yukon Today?

    What’s the best front center console cup holder insert or complete replacement for 03 GMT800 suburban? I keep tipping standard size drinks in these oversized rt44 / rt66 big gulp holders that came standard.
