I recently bought a Sierra 1500 Denali because I love this truck but I am now noticing parts are really hard to find, I want to replace or delete my quad steer but have no idea where to start or look. I haven't been able to find anything in hours. Any help?

Okay guys I bought this truck from a dealership in September. It was used and I got a 30 Day warranty. After the 30 day period, this is what’s happening. I got in my truck and noticed a rough idle. My truck would shake and out of no where the check engine light starts flashing and my traction control light comes on. I took it to my buddies and we got a P0308 Misfire Detected Cylinder 8. So I did some research.. I also had a code which was P219B. Air/fuel mixture ratio.
I changed the spark plugs.. didn’t work. I moved coil packs.. the misfire didn’t move. So we watched Live data on the scanner and injector 7 was acting up. So we replaced all the injectors on that side and this truck is still missing.. I’ve ran seafoam through it and cleaned the throttle body and MAS. My buddy things I have a valve issue or something wrong with the cylinder…
there is no AFM deleted or anything of that sort. The truck has worked flawlessly until now. 135,000 miles on it. The rocker arms all
please someone give me something to try. I just want my truck fixed lol.
posting a link below of what it’s doing…
TIA for your help and time…
BLUF: Ticking noise under truck, not heard from top of engine compartment.
I noticed a ticking/clicking/pinging noise under my truck today, took a video, hopefully you can hear it. Anyone else?
Truck was in Park and Neutral (Parking brake engaged) and still heard the sounds.

Hello all I'm new to this read forums my entire life when needing help on a issue someone had back in 99. But anyway I have a 2008 Yukon xl 5.3 bought it a few years back quickly realized there was a issue on top of issue. I got screwed and screwed big time. Truck was sold as 168k miles. It was clean nice good looking truck for 4800 bucks. Turns out won't go over 65. We'll we just said screw it and run it for a while until we got our excursion. So now I've been trying to fix it. I need help I've tried refresh at the dealer it sat there for a entire day in a bay with a tech and they couldn't figure it out. So back to the drawing board. Later on tried to trade it in they pulled the carfax trunk our dude swapped the cluster and it was said the last reported mileage was 278k. Well ******. I want to figure out why it will not surpass 65. It has all the gears. Engine has all the power. No limp mode no codes. I have even pulled the cluster and drove it and that didn't change anything. Please help. Thank you. Derick r.

Reciently the Check Engine Lamp (MIL) came on at start and remainded on with no noticable engine running rough. The error codes were read which indicated 400+ Cold Start error codes on Cylinder No.3. Their are several GM Service Bulletins (PIP5498M, PIP5628E) on this subject V8 on engines from 2000-2022. The bulletins indicate the "Cold Start" causes misfires due to coolant entering the at the liner to deck face casting or the casting line in the intake port of the cylinder head, in my case No. 3. The GM Service bulletins indicate "engine replacement" is needed to fix this problem. I have been very happy about this vehicle however, at 67K miles, this type of issue should NOT be occuring. Apparently GM has know about this problem since 2000-2020 model years described on the attached Service Bulletins.
After Two days of MIL being ON, the lamp is now OFF. My question is how can the problem described repair itself and could the diagonistic codes be attributed to another problem? I was under the impression that once the diagonistic code is initiated, the only method of turning OFF the MIL is by resetting or clearing the codes.
