i have about 133k, recently changed it but had an oil leak from the oil filter so i changed it again when i fixed the filter, i did just order a AFM disabler. and I did some reading last night that they were talking about the filter i just got to get my way to the back to undo it and clean it out.
I took it to the dealership to get checked but they said their is nothing wrong with my AFM but yet my truck still takes a second to go from v4 back into v8. could it be the VLOM filter or even the lifters themselves?
So for some reason my 2011 gmc sierra lately has been going into v4 at random times just for a few seconds then back to a v8. I took it the the GMC dealership and they told me nothing was wrong with the AFM but it still is doing it very randomly and when it goes back from 4v into v8 it takes a second and jerks a little bit. should I just get a AFM disabler or what im so lost on what is wrong.
