I am hoping that you can help me diagnose what is causing a hesitation on my truck when accelerating from a stop. It sometimes also hesitates when shifting at low speeds 10-30mph
2014 silverado 1500 WT 4.3L V6 locking rear end 32,000 miles no codes, using bluedriver scanner red
two weeks ago truck took two tries to start never done this before has not happened again last week truck started hesitating on acceleration from stop every time rpms drop from 1500ish to 500ish and then jump back up and truck accelerates I have attached one of the drive logs where you can see the fuel rail pressure drastically change when the engine rpm drops You can see the seven times the truck hesitated at the drops in the graph Started logging other items to see what is happening and found this spike in the temp sensor, attached picture also. intake temp sensor is yellow line and engine rpm is blue line. I highly doubt the temperature actually went from 55F to 135F during my commute.
What I have done
Checked transmission fluid, truck level and hot. Fluid in the dashed good zone between the holes. No burnt smell. Found the strange temp reading. Truck off Unplugged the mass air flow sensor and drove around large parking lot. Hesitation completely gone truck drive normally for 5 min. Check engine light off. Truck off Plug in mass air flow sensor and drive around parking lot again. Hesitation back Check engine light on with codes for MAF unplugged. Thought MAF was the issue. Bought new MAF and air filter Installed MAF and air filter Problem gone on test drive for 15min, truck fine, no codes. Next day, hesitation is back, no codes Realize I need help. Post on forum.
I'm sure I have left out some important information, just let me know and I'll try to answer.
I greatly appreciate the help. Thank you.

Hello all. I own an 18 Silverado 1500 LT , double cab, 6’6” box, 6 spd transmission, I have opted to put 26” status alloy empire wheels with tire size of 305/26/30. Stock transmission gave out. Stock Transmission went out. They said torque converter and pump went out then everything else went with it. Was able to replace the entire unit with a remanufactured from GM. 1 month later, back to the shop (dealer). They covered the repairs because it was under warranty but if it goes out again they won’t because they believe it is the rims causing the trouble. However they will cover if it goes out with stock wheels. Which I will be putting back on. Has anyone else experienced issues with this type of truck and 26” wheels? I did research the “Unsprung weight” makes some sense, however only the transmission gave out, not my drive shaft, drive shaft knuckles, diff, just the goofy transmission which I know the 8 speed has had their share of ongoing things. How is it that a truck that is capable of towing 9k lbs has issues with no load on 26” rims. Pulling a payload in the bed of the truck and pulling a trailer should still have the same effect. If I can’t tow anything with the truck, then what is the point of a truck. I have went back to stock rims to see what would happen. Anyone with info ,thought , something sketched on a cocktail napkin would be greatly appreciated. I do thank you all for your time on this. I have attached the service ticket to this post.

Hi hello, recently my v8 2001 1500 suburban rear end got destroyed, i have a v6 2004 Silverado 1500 with no motor, i was wondering if i can just swap the rear ends on them, anybody know if it will it work? What could be the problems if i do it and its not compatible???
I have a 2001 silverado extended cab v6 that is a base model. It came with no power locks or windows. I am trying to convert them. I already have panels,switches and the harness out of a 2002 z71. My problem is I found out my fuse box won't support this. I can provide pictures if necessary. I'm looking for advice on if I can just get another fuse box out of a truck that has the options and do I need to get a new underdash harness as well?
Also if anyone has done this swap before any other insight would be greatly appreciated
Its a project truck and has sentimental value so I'm not just going to " go sell it and buy a truck with all the options"
