Did u figure it out?

Not yet.  This weekend has been extremely busy, so I have not been able to trouble shoot.  I am hoping for some time this week and next weekend.

Nope, all US units....  My boss does a TON of driving for work, and replaces his truck every 5-7 years, as his mileage is quite high.  The body and interior are immaculate.  The engine does have a lit

Has anyone had luck with the dealer addressing this issue? Just noticed this on my 2018 as well as a squeaky/creaky brake pedal (the creak seems to be coming from up higher near the brake booster).

 

I was just going to live with the annoying creaky brake pedal, but after the squeaking started I think the both of them may warrant a visit to the dealer.

 

I found someone on youtube (posted below) that posted a video about the same issue and while reading through the comments he stated that he eventually got the dealer to replace some exhaust components which solved the issue completely.

 

It’s unfortunate these two issues happen often (Almost every time you accelerate or brake) and become highly irritating. My truck is still under warranty thankfully. Am I being too critical or would this stuff bother you guys also and deserve a trip to the dealer?

Anybody have any luck? I've been fighting this for a couple years. At least on mine is definitely not the flapper valve because I cut it out when I put the new muffler on. Mine gets louder the higher the rpms.

I have a 2014 Silverado LTZ (very high milage - 219,000)  Runs great and still has some power left under the hood.  For the most part, it is in great shape.  It have a strange noise when acceleration or getting up to about 3 or 4 thousand RPM.  It only does it under load, so it is hard to find where the noise is coming from.  In the attached video, it takes place at 12-18s and then again at 40-46s.  It is hard to hear because of the wind noise, but I can't figure out how to isolate the noise any better.  If anyone has any ideas, I would sure appreciate the input.  The water pump was just replaced, and so was the alternator, along with the tensioner pulley.  I admit my limited knowledge under the hood, but I am willing to learn and fix it, if I can.

Hey I'm currently having the same issue with my 2015 Tahoe and can't figure it out I was thinking it may be the vacuum pump pulley but it only makes the chirping noise while in gear and accelerating I've replaced the tensioner,  that was my first guess but still not it, if you had it figured out and could save me the headache and time and money guessing and replacing parts that would be greatly appreciated

I had this same chirping. Just finished a new camshaft and DOD/AFM delete. No more chirping. 

 

There's a possibility the failed lifter was hitting the lobe of the camshaft (mine had a bent pushrod on the failed lifter) and this is why I chose to upgrade my camshaft while fixing the lifter with the DOD delete.

      Would this CV Shaft be bad?

      Yes. You need to check out that thing, and the hub further.

      Would this be normal or a worn CV Shaft? 51K miles 3.5" lift? Boots are intact and no visible leaks showing. Attached is a the video I took. Thanks     https://youtu.be/ZnW7PPRmjJY?feature=shared

      2010 Avalanche 5.3 not running correctly after engine swap.

      By Jsdirt · Posted

      If everything checks out at the MAF, then the MAF is BAD, new or not.   You don't need a signal generator to troubleshoot this. PCM needs ALL powers and ALL grounds able to light a halogen headlight bulb - if it can light the bulb bright, then the wiring is good enough to run the PCM.   Best thing you can do for yourself is spend some time here: scannerdanner.com - Check out all his YouTube videos on similar issues. If you decide to subscribe it's the best bang-for-buck ratio in the automotive world, hands-down. He's got TONS of free vids on YouTube, too.

      2010 Avalanche 5.3 not running correctly after engine swap.

      By contrabombarde · Posted

      Yes, I used my multimeter to probe all of the wires at the MAF, both with the sensor connected, sensor disconnected, key on engine off, key on engine running, etc etc etc. I probed all of the wires again at the PCM, at the connectors, etc. All voltages are what they should be according to the service manual/wiring diagrams. All grounds are good, less than 20 millivolts from the battery negative under load. Both at the connector of the MAF, at the PCM connector etc.      I know this throws a pretty big wrench into things, but this truck was acting up before the swap. I don't have very much information, if any on what was causing it, but if you cleared all of the dtcs it would do the same thing where it would crank, fire, then die. And it would do the same thing a dozen or so times, and eventually it would start and run, but the difference is that it would run and actually be drivable. Whereas now if you can drive it at all, it goes into reduced power mode almost immediately, and even then it's not running correctly. When you come to a stop at a light it stumbles down to for 500 RPM before catching itself and returning to the smooth idle. And if you go more than about 50% throttle then it immediately goes back to doing the misfire thing.    Like I said, I know that throws a wrench into things, and unfortunately I was not able to pull any data or anything like that before I did this work, so I don't have much to go on.    I'm trying to not fixate on one particular thing as the cause of the problem, but it seems like all avenues are pointing me towards the PCM. Like I said I have tested the wiring extensively (see above), and during cranking the sensor does produce seemingly legitimate values at least according to my multimeter, but as soon as the engine fires those values quickly descend into gibberish. I've tried it with multiple different known working sensors, I have done literally every test I can think of multiple times on the wiring (probing the signals, probing the pins with the sensors unplugged, probing the pins at the PCM, voltage drop, voltage drop under load, continuity, ohms, and double-checking everything against the wiring diagrams/ proper values in the service data.)    Another thing that pushes me towards a possible PCM failure is, I have noticed in troubleshooting a little bit taking a break and coming back, that when I leave the truck to sit for a while and cool off, it starts and runs smoothly when I first start it up. However once it warms up. It starts having problems. For example, when I went out to the truck this morning after it had been sitting overnight, I was actually able to drive it down the block. And then once I got on the throttle a Little bit after going about a thousand ft, it started misfiring again. I pulled it back into the driveway, shut it down, and started it back up. It idled smoothly. As soon as I touched the throttle it did the misfire thing again. From then on as soon as I started it it would misfire. I shut the truck off and went to go get a coffee and do a bit more research. When I came back out I started the truck up and it immediately went into the smooth idle. After a couple of minutes of playing around with it, it would not idle smoothly anymore. Let it sit a couple of hours, rinse and repeat. This makes me think with temperature change something is going wrong inside the PCM. I have the PCM out of the 2007 donor vehicle and I'm thinking of getting a one-day subscription to the ACDelco programming service to try and program that and see if it helps.   Like I said, I'm really trying to not fixate myself on one potential cause, but it seems everything is pointing me towards PCM failure. I would really like to try to confirm that, but unfortunately I don't have an oscilloscope or a signal generator to do the GM service procedure where you feed 5 khz into the signal pin.
