Like many of you, I was affected by the faulty high pressure a/c hose design on my 2014 Silverado. Fortunately for me it was only February in Texas and I barely needed it. Even more fortunately though

I updated my post to include a picture and procedure for the swap. As far as programming, mine was plug-and-play. Hopefully that is the case for everyone who tries it.

Very interesting. Did you have to shim the new pedal to prevent flexing? Sent from my iPad using Tapatalk

I have a 2015 CC 5.3 with pedal # 23362231. I've had the truck programed by Black Bear, and the pedal still feels sluggish. Probably the sluggish feeling pedal of any vehicle I've ever owned. My 2014 4.3 pedal felt similar. It's been about my only complaint with the truck. Black Bear tune helped with it, and with the tranny shifting, but not as much as I had hoped for. I guess it's just the nature of the beast(our trucks).

I spoke to my parts guy at my local gm dealer. He said the pedals have to be programmed. So what you guys with the new pedals are feeling may just be the symptom of an I programmed pedal. Possibly the trans shifting a little firmer from the pedal not correlating correctly. He also mentioned that there may be an updated reprogram for the pedal. Im calling today to find out.

I still havnt had a chance to call. I have to talk to a service manager about the reprogramming. My parts guy told me the pedals needed to be programmed. So I’m thinking that it’s just a non programmed pedal people are feeling. And how it feels better. I could be wrong

It's true a pot wouldn't need programming, but the computer may need to be recalibrated to the resistance arc on the pot. No two are ever perfectly equal.

No programming required on replacing the accelerator pedal on these K2 trucks.  Plug and play replacement.  Verified right from GM service procedure.

Ok. Sounds even better. I was just passing along info from my parts guy.

I have a 2015 Sierra z71 CC and it seems to have the old 20972082
Was manufacturered 4/15
Bought dec 15 brand new

So I’m assuming I need to hunt a gas pedal. Been playing with the idea of taking to a shop to have a guy tune it good to see i could make the accel better. Interesting read

I have had the new pedal installed for a few weeks now and I am still noticing a positive difference. It is still not perfect but much better than the old pedal. I would give it a try for anyone that has the old design. Thanks to the OP for looking into this and posting his results. Much happier with my truck now. Its a 14 Sierra AT CC SB 6.2.

My Pedal was just replaced by the dealer in my 2016 with the updated part.  The lag is 98% gone.

 

Only under a hard braking and fast back to the throttle I can feel it a bit but no 1-2-3 second dead spot.  More like half a second dead spot.

 

Not sure what they changed but this pedal seems to send signals faster.

 

As for acceleration I see no difference through the gears it still will not spin the rears lol...

So I just replaced my pedal and the dash says "engine power reduced"...great! This is just with the truck still in the garage and key switched on for lighting. Anybody else get that message after swapping?

 

edit: after driving, the engine light is on, but no message. Driving seems fine but I just went around the block. I'll probbapy swap back until I get more info.

Brews,

 

Sorry to hear of your trouble. I looked up the part number for your '14 and, regardless of whether you have a V6 or V8, it lists 23362231 as the correct pedal for your truck. Perhaps you have a bent pin or just a defective part?

I doubt anything is bent, because swapping back to the factory pedal makes the light go away. I also disconnected the battery for a bit and that didn't solve it. I'll give it a couple days I guess and then try to return it :sigh:

 

edit: Oh, mine is the 5.3.

This is eye opening and quite upset I'm so late to reading all this. Amazon got them in stock for 53 bucks. Well worth a shot. I have a 2014 Sierra 5.3 with adjustable petal, I've read plenty about the wood trick and all. I've always said this truck is god awful slow for acceleration time. I go in my girlfriend's newer v6 Grand Cherokee and it's like a ROCKETSHIP compared to my truck. This is WELL worth a shot. I checked and I have the older part number. Not alot of flex to it but I think I'm going to give this a go as well.

Sounds good. This seems like a reasonably affordable "fix" for the throttle lag if it works.

Then I can throw my paint stick into the campfire LOL

I've never actually did the paint stick trick. But my 2014 always had that lag. I have adjustable pedals. But I can literally press the throttle down half inch almost before be revs. I've driven a 2017 and it felt exactly what I wish mine did. Fingers cross this does the trick

      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.
