GM product about to kill my 90k mile 2007 sliverado: displacement on demand (it sucked in the 80s, still sucks now). system fails on an otherwise very young engine, check engine light for misfire on cylinder #3. failing lifter or the bumpstick is becoming slowly less bumpy
replace with factory parts: will fail again soon. this is not conjecture.
delete system (essentially making it into an LS2 which was available on a bunch of other GM cars that year) and fail smog because computer code has to change which fails CA check sum requirement (thank you new procedures for 2021)
i've been luke warm on this truck since i bought it. vague steering, numb experience overall. wahOOOOOOOah GM shifting sound of power!!! i kinda really hate it now, which is a form of dropped jaw
tangent: failing DOD system can cause the stability control and transmission to behave erratically. wtf. why?
Bro. C’mon. Don’t delete. Just disable. When it comes time to smog, just unplug this damn thing (they need the OBD port anyways).
