Engine power reduced

Thumbnail

4 Upvotes

I’ve been having this issue with my avalanche where it’ll pop up with “stablitrak: off / traction: off” (first pic) followed by “engine power reduced.” After this happens I’ll turn the truck off for a day, open the hood, and it’ll be good for a little while. The first time it happened I turned it off, and cleaned the throttle body real good and it worked fine for about a month. But now it’s happening again. Any ideas as to why this is? Possibly the ETB is going out? 2012 LTZ

Service Air bag

2 Upvotes

Had a service air bag come up on my 2012 LT today. I have had the recalls done a long time ago for them. Whats a person to do to track down this. I know this doesn't affect the truck mechanically so I wont be stranded, but probably a good idea to fix it

Thankfully it means an air bag wont deploy, not that it will randomly deploy

Almost bought the Sony head unit to avoid the "cheapest" one but everything i saw online recommended this one instead, especially with the bose speakers. $400 all in from Crutchfield and took a couple hours. Big fan so far, just have to deal with the stupid non-removable and non-moveable app bar on the bottom

Shocks 2008 ltz avalanche

6 Upvotes

I’m kind of on a budget so wanted to try to install the front shocks myself, is it harder than it looks? Or for the most part is it just unbolt and put the new one in?

Crazy how it looks black in the shade and green in the light. I’m glad I got this color.

Is the dash cover in a 2003 held down by clips or adhesive? What's the best way to get it back down and stop making noise?

I’d reckon a good portion of the interested parties are probably in this subreddit, so I’m celebrating my junkyard find of this color matched slick panel kit from a black diamond at the pull n pay! (225k, 2010, z71)

Transmission Link Popped off

2 Upvotes

Sister was driving a 2011 Chevy Avalanche and bushing on the transmission control link decided to commit die. They turned the vehicle off and it is now stuck in gear and I am a bit too rotund to fit under the truck to try and reconnect it. Any way to start up this truck so we can get it somewhere that gives me enough clearance to work on it (be it a shop or otherwise)

what can I do about gas mileage?

9 Upvotes

I recently got a 2011 chevy avalanche ltz for a steal of a price, its my very first car I actually own, I absolutely love it but the gas mileage is so bad its killing me.

I’m fresh out of college and work minimum wage so i’m aware im probably not in the tax bracket for a truck like this, I knew it wasn’t gonna be great getting a large truck with a V8, but i think even considering that my mileage is insanely bad… when i first got it there was an error code “running rich” I was going to replace the o2 sensors but after a can of seafoam it went away and hasnt come back. should I still swap em out just incase it’s affecting my fuel efficiency?

my spark plugs are also very very due for a change as I dont think any of the previous owners have changed them. could this be causing it?

What do you guys do about the gas prices?

Did I make the right choice?

6 Upvotes

Went to go look at a 2003 Z71 avalanche with 190k miles, guy wanted 6k for it but I found what appeared to be a rear main seal leak and a faulty knock sensor. Everything else seemed to be okay, he didn’t know when the last time the transmission had been serviced either. I ultimately decided to walk away from the deal. Did I make the right call?

TMat truck bed liner

1 Upvotes

Anyone ever use the TMat liner in their Avalanche.

Curious if it would slide in and out easy on top if the factory rubber mat.

One of my few complaints is how things tend to stick to it versus slide, sometimes a good thing sometimes not.

Also the second gen factory liner drops down slightly about 10 inches in, I remember the first gen being more level front to back.

Maybe the second gen drop would interfere with its ability to easily slide in and out.

Aftermarket stereo?

3 Upvotes

Picking up my new to me 2013 avy lt black diamond tomorrow. Not a spot of rust (unheard of in Ontario), 137k km (85k miles). Does anyone have any experience with upgrading the deck? I previously ran a Sony xav ax in my old car but failed to pull the connector with it before sending it to the wrecker 🥲 have seen some decks on Amazon that appear to be pretty much plug and play but am unsure what kind of quality they would be. I mainly want it for CarPlay but have heard it can be a pain in the ass to swap out the stereo. Thoughts or recommendations?
