I have a 2015 3.5L Lariat. So far I have had to change the throttle body out twice. The truck just randomly shuts off and just idles and shakes severely while going down the road. The computer system freaks out. The only resolution to get it back running was to hurry and pull over shut the truck off, turn it on, shut it off again and turn it back on and then everything is fine until the next random shutdown. Took it to the dealership and they keep replacing the throttle body and it works fine for about a year then it happens again. Has anyone else had this issue? Should I just get an aftermarket throttle body instead of OEM and hope it works?

 

I went with an aftermarket one https://www.americantrucks.com/bbk-7...dy-1114v6.html . Replace it and keep the OEM one as a backup just in case but you'll probably never need it.
