I agree that a good video would be worth a million words of what the problem is and where it's located.   I filed the NHTSA complaint shown below:     VEHICLE SPEED CONTROL: 2014 Chevrolet Silver

I can't believe this post is still going strong almost 3yrs later. Glad my fix is helping others.

After noticing the gas pedal has a lot of travel before it actually starts to work, I looked at it closely. I noticed it's a very bad design. There is a plastic bracket that is bolted to the floor pan/firewall and it has two studs. The metal gas pedal assembly bolts to this plastic bracket. The Bottom right area has no anchoring, and has a gap between it and the floor pan. so when you step on the gas pedal, this whole bracket flexes like crazy. I did come up with a solution. I cut a 1/2" long piece off the end of a free paint stick from home depot. Wedged it between the floor pan and the plastic bracket on the bottom right area. super glued it in place. guess what... NO MORE FLEX. Unreal how I have to do this to a $46k new 2014 truck. Never owned a vehicle with such a poor gas pedal design. Pic below.

 

My 2017 has a different looking setup there (power adjust pedals also) but still has a considerable amount of play. Did you loosen up that bolt, wedge it in and then tighten ?

My 17 also has the power adjust pedals and I just wedged a 1/8" thick piece of rubber folded in half under the right corner. Made a huge difference.

I think I'm going to remove the pedal if it's easy and design a 3D printed spacer that will fit in there perfectly. 45ec96de2fcd66089e88d3c46b1ca888.jpg

I just did this on mine, non adjustable and it is awesome! I can't believe how much better the pedal response is. Why did I wait 2 years when this changes the feel completely. Just a 1" by 1 1\2" piece of 3\8" rubber.

OMG. A freakin paint stick fit perfect!! There is your mold.

But there's always more. Someone will want more bling; fancy materials, logo by big-shot company, etc.

We've got 3-D printing on the way!

 

Just how many pieces can you get out of one paint stick? Thanks for thinking of a solution with what you had at hand. I agree fully; the paint stick mod works perfectly.

Just checked my '14 LTZ. Now I'm looking for a paint stick! I had over 1/4" movement.

 

Gotta love the expert's explanation.....It's designed that way for vibration.

 

Some rubber washers would do that an not have so much unnecessary flex.

Flex adds to the problem by increasing the rebound/fluxiation in gas pedal input.

Like she said, "Firmer is better".

I just bought a 17 Silverado. I thought the sloppy pedal was just me adjusting from going from a Trailblazer with an inline 6 to Silverado with an 8. I'm definitely going to look at this.

Ok guys, update here regarding my 3D printer shim.

 

My plan was to remove the lower bolt (which I had assumed was attached on the back side to the firewall). Print a custom fitted shim that would go around that bolt and then when the nut was snugged down would hold the entire thing in place.

 

 

I was mistaken: as you can see mine looks differently than the OP (2017 GMC Sierra denali with power adjust pedals might be the reason for the different look). I don't think it matters which option you have, the OP hit the nail on the head with the simple "paint stick" mod. That lower bolt is not attached to the firewall, but instead it is embedded in the black plastic honeycomb bracket. That bracket is unsupported at the back (as was the OP metal bracket). With any type of pressure on the pedal there is considerable "flex".

 

Considering that a custom 3D printed shim would do absolutely nothing more than the paint stick mod (other than waste my time and cost a few cents lol) I have decided to skip the 3D adventure and just use a paint stick

 

Thank you for the super simple & easy to do mod ! You rock !!

 

With that in mind if you guys think of anything along the way that would really benefit from a custom 3D printed part, hit me up !! It's a hobby / small business of mine and I love helping out where I can !! Don't forget, there is essentially nothing we "cannot print"!

      2018 Silverado Console USB Port Not Working

      By Tbhats2130 · Posted

      My centre console USB ports haven’t been working and the one in the glovebox is starting to act up. When I plug my phone into the cord the radio will go black and stop playing, and the CarPlay is inconsistent.   I checked the fuses and they were fine. I changed the USB port out and still nothing. Hoping for some advice on what I should be looking at.

      The truck is a 1995 Chevrolet S10 Blazer, 4.3 VIN "W" engine. :cracks knuckles:   On a whim - because I needed a headache - this truck was for sale so I stopped to take a look. Doesn't run. Well, it does, but barely. Long crank, choppy idle, bad misfire(s), it REEKS of fuel. I can DO this..I'm thinking. Diamond in the rough. One owner until last year. A young guy is selling it, he bought it 6 months ago. It stranded him more than once, he's got a newborn. It was in the shop 10 days ago and he "thinks" they said it needs a new fuel injection system. He can't put any more money into it, needs it gone. I was thinking of upgrading my Macbook, which is a total want, not a need. For less than the price of a new laptop I can have fun for months tinkering on this truck and enjoying it. I'm taking this truck home. The guy was beyond thrilled, his wife was there, she thanked me profusely, I could tell they were hurting. They seemed like good people in a bind.   Some parts, a wash, maybe a set of tires, and I can have a few months of fun and then turn it for beer money (or the next project).   Sure enough, there's a work order from a shop last week in the INCHES of paperwork on this truck dating back to when the first owner bought it. They put a new distributor in it, fuel injection work describes basically opening the plenum and putting it back together. He said he couldn't afford any more work so he had them button it up and that's when he put it up for sale.   I'm not well versed in 4.3. I did discover 1995 uses the 1992-1995 SCPI "Spider" injector which is riddled with issues from splitting lines, clogged or cracked poppet valves and plastic spider legs that crumble over time. Cool. I'll just order me a ne---. Oh, the auto parts store doesn't have it? Rock Auto doesn't have it. eBay? $$$$$$ for used. These are UNAVAILABLE period end of story unless you know "a guy" who's still got one in a box somewhere.   Can't upgrade to the '96-'04 injector, it's a different plenum, wiring/pinout and sensor config.   There are a few kinda "know a guy" -guy rebuild services for these injectors out there for about $350. Okay, Okay... I'd like to know if anyone has used them? Anyone got a lead on these crappy 92-95 spiders?   I also don't want to send MY spider to Narnia and back without knowing if that's truly the problem. I guess I'll need to pull apart the plenum and do some digging.   I was also thrown for a loop. This 1995 model year truck has an OBD-II connector. The interface is decidedly not OBD-II. I can read and reset trouble codes and view live data, but there's not a lot of data. Like misfire count and on what cylinder, that's not there. It's OBD-1.5.   Nothing is ever easy. Now it makes sense why this guy wanted to disappear this thing for cheap. I'm guessing the shop told him the injector is toast, the part is unobtainable and they're not going to sort sending the thing to a rando offering rebuild service on craigslist, and the kid likely can't be without a working car for 3 weeks even if they'd facilitate that.   Experience with these early SCPI's? Stories? Things to check? Sympathy? (..Nah...)   This can sit until I sort it. But I haven't had a problem with a vehicle I couldn't easily solve in a long time.

      I have four that read by the dash 8 to 10% better than miles/pump calculations and I have one that is spot on.
