I did all you did too and didn’t work for me. When I replaced the valve it stopped for like 2 days then went right back. Finally I had to take it to dealer and have them rest the computer for transmission. Completely fixed my issues.
Hello I’m a new guy. Just bought a 2020 xlt having same issues. Was pointed to this thread and I purchased the erg valve , but I can’t find it for the life of me ! Anyone want to share a video with me and help me out ? Thank you !
