New spark plugs

I put new spark plugs in my truck, and didn't know the torque specs for them. I have the L33, which is aluminum. I looked up the torque specs, and got the confused with a 5.7 vortec, which is cast iron. The torque specs for the 5.7 are 25ft-lbs, and the L33 is 13ft-lbs or in that area. You think I overtightened them? I put Bosch platinum 4's in. It isn't misfiring at the moment, but it had kind of a rough start this morning, but it's a little cold out, like 40's. I'm just learning and preparing myself for when I screwed myself for the stupid torque specs.

Over torquing the plugs has nothing to do with the miss. You have another problem.

I would remove all the the plugs, put anti-seize on them and re-torque to the correct spec. The longer you wait to do this the harder to loosen and remove them. :happysad:

Also I'd stay away from Bosch 4s in the future

      (Update lift problem)Dealer installed 2” lift question
      By Tattoo magic
      I have a 2022 Silverado 1500 four-wheel-drive. The dealer ordered the 2 inch lift kit they offer and I’m waiting for it to come in and have it installed. But I noticed that the kit doesn’t come with upper control arms. Is that going to be a problem?
       
      (***UPDATE*** )
       
      so I had the factory lift gm offers installed. When I picked it up, it looked great but as soon as I went to drive it off the lot. I could tell something was wrong it felt completely different. I figured it was just a break in period. But even after a day or two, I was getting crazy bad vibration at low speeds. Took it back. They ended up putting one of the U-bolts on wrong (I have pictures if wanted) they fix that and told me the vibration was gone. I get my keys go to drive away vibrations right back. I turn right back around. this time they have a mechanic ride with me. He clearly hears  an feels a vibration, says somethings wrong so we turned around and he takes it back in. Three hours later they bring my truck back they had to remove the back blocks said there was no taper to them and it was messing up drive line. I got it back and the vibration is still there. (Now annoyed that only the front is lifted and still vibrating). I have them take the whole lift kit off. Put it back to stock. (Now remind you my truck has been down and I’m missing work for 5 days at this point) And after that Whole ordeal, I was done with the truck since I couldn’t have it how I wanted it and decided to trade it in and they made me a good deal on a 2023 5.3 LT.z71
       
      I know many have gotten this lift installed said it worked out for some reason it did not for me. I’m much happier with the new truck.

      2017 Chevy Silverado 1500 4X4 Goes into gear but won't drive
      By ChevyGirl777
      Hello, I have a 2017 Chevy Silverado 1500 4X4, 110,000 miles, was driving down the road and suddenly stopped moving, truck still on but won't move. Goes into drive and reverse but wont move. No check engine light, transmission fluid full, and clean, no crazy noises. Any clue what it could be? I have been told the linkage, or the transmission pump... Any advice is appreciated.

      Driver's seat leaning to the left?
      By Jgardow92
      I have a 2022 trail boss lt that has about 6100 mile on it now. Bought it brand new in may 2022 and it seems like the drivers seat leans to the left towards the door. Almost feels like Im gonna fall out of it and no matter how I adjust it it seems the same. Visually it looks like it sits level and is fine. Is it possible something is broken inside like the frame? I would assume the frame would have to be sturdy. Is there any place that sell a better bottom cushion?

      Passive Entry Rear Handle
      By drmilesbennell
      Hey all,
       
      I have a 2022 Sierra SLT with passive entry locks on the front handles. Does anyone know if I can easily add passive entry locks to the rear handles? Acquiring the actual handles would not be the issue but I'm wondering if there is a harness (or whatever powers the front passive entry buttons) in the rear door to begin with. I know they come standard on Denali, so was thinking GM might just leave the wiring in the door for different trims but not include the passive handles all around. As I type this, though, I'm sure there's programming that needs to be done but figured it was worth a shot - because why not!
       
      Any help is appreciated, thanks!

      FS '18 Sierra OEM LED Taillights - Custom Painted!
      By youn1033
      or sale are my set of custom painted, OEM Sierra Denali LED Tail Lights. I had these painted to go on my truck and unfortunately they took so long I had to go a different direction before I got them back.. I have since moved up to a 3/4 diesel and am hoping these can find an owner who will appreciate the time, effort, and $$$ that went into creating them!
       
      These OEM LED Tail Lights are selling for $300 - $500 a piece online, and the cost to have these custom painted Mineral Metallic to match the Denali paint + the lens smoked (lightly, not enough to dim them when lit!) was $700 - looking to get $1,000 including shipping. Can cut a better deal if wanting to pick up in person in the Houston, TX area.
       
      Please reach out for additional pictures, questions, etc. I respond much quicker via text (405) 642-9097
       
      Thanks!
