noleguy83 posted a topic in 2014 / 2015 / 2016 / 2017 / 2018 Chevrolet Silverado & GMC Sierra 1500So... i was just pushing the truck a little bit and i noticed something that has me alarmed. I got on the throttle pretty hard from a slow roll and when it hit 4500rpm i got a vibration and noise somewhere to my right or behind me. It is quick and stops at like 4800 or 4800. Then just normal awesome engine noise. And that also is the only time it does it. I want to post a video but i also do not want to do it again. Anyone have any experiences like this or ideas? Thanks Sent from my SM-N920V using Tapatalk
Update: Picked the truck today. New motor mounts installed and shimmed. I also had the upper injectors/tb/and that part of the fuel system cleaned. Appears the previous owner used crap gas or never had it done or both. I saw the readout on the compensation of the throttle body for air/fuel mix. I was about to have a cel... anyway that and the mounts has definitely improved the vibration. It is still there but a lot less intense and definitely not as loopy. My buddy who works there also hooked me up (off the record) and set min idle to 590 and the vibration is 100% gone. So i think it is really a few things that compound in this issue. I doubt my injectors/fule system were a part of it. But the three things combined and now its gone. Not saying it will be the case fir everyone just wanted to share my experience. Also the dealer will not adjust the idle like this on the record. Also as i said before. The way i feel is ill take the new mounts either way since there is an inferred defect in the originals... Anyways. Hope it helps and on to the next mod... Sent from my SM-N920V using Tapatalk
There are a lot of different vibration posts but some of the ones I am referring to are: http://www.gm-trucks.com/forums/topic/156666-2014-rough-engine-idle/?hl=rough+idle&do=findComment&comment=1406801 http://www.gm-trucks.com/forums/topic/195971-rough-idle-new-motor-mounts/page-2?hl=rough%20idle Also in talking to the service manager he said the mounts may or may not help. He has seen it go both ways. He also mentioned injectors and the low rpm setting from the factory. They are trying to be precise with all of these things and it seems that they are fighting each other a little. In my opinion if there is a defect or design issue with the original mounts ( as he told me and research confirmed) I want them installed either way.
Agreed. My service people have been great so far. I should have it back tomorrow so i will give an update then. Sent from my SM-N920V using Tapatalk
The recreation is essential to getting them to admit the issue and fix it under warranty. They are starting by replacing the motor mounts with the new design.
noleguy83 replied to Chris Pino's topic in 2014 / 2015 / 2016 / 2017 / 2018 Silverado & Sierra Issues, Troubleshooting, & Recalls/Service BulletinsI had a similar issue with my avalanche. It was on one of the rear parking brake assemblies. The shoe had failed and a piece was rubbing the rotor from the inside near the hub. Sent from my SM-N920V using Tapatalk
Glad I am not the only one...
I purchased a used 14 Silverado CC Z-71 2WD and I absolutley love it. I did however notice the warm idle vibration. I almost wrote it off but after reading all of the forums on here I took it in. My bumper to bumper warranty is up in a few months so this really saved me. Dealer just called and said they were able to recreate it and are moving forward with finding and fixing it. Side note: Are you all zombies at work like me? I am glued to these forums... lol
