I'm gonna make this as short as possible for everybody reading this. 2013 GMC Sierra 1500 LTZ crew cab. During cold start no CEL comes on, no issues, runs great. Once it warms up after about 15ish minutes, the truck starts to bog and sounds cammed, raising and lowering the rpm trying to keep it alive before eventually dying. The truck is bone stock, and doesn't even have bigger tires on it. We've replaced the fuel pump, fuel module, and I believe more at this point. Been fighting this same issue for well over a year at this point.
Multiple Chevy mechanics and dealerships have tried and failed, as well as a few data loggers have gone in and tried too find anything wrong with it and that's how we replaced what we have computer-wise. We are at a complete loss with this anymore and are about 20k into a truck we have no interest in actually keeping.
I've read some things about these with similar issues, a lot of people pointing at the same things. Could it be the body control module? Could it be the actual fuel supply pump? Any help with this issue is very greatly appreciated and any direction you guys who might've had similar issues can point me in is also very appreciated.
Thank you to all who read
