So I'm new to these trucks. At idle, I can feel the engine running like vibrating almost. Seems to mostly be when it's in drive. Is this normal? Like is this just how these old diesel trucks are? When I have it in park and have the hood open, the engine isnt moving and it runs and idles fine. The high idle doesnt usually come on though but idk if that makes a difference or not. So the motor mounts on it are good right? Even if I cant see the engine moving? Dont think I have any misfires either. Code reader didnt pull any up and engine seems to be running normally. Just thought maybe it was the vibration from the engine running. There is definitely a vibration near the end of the tranny too in certain gears when it's trying to upshift if I step on the throttle more. Guy I bought the truck from says possible bad TPS and that it could cause that. Code reader was pulling a code 23 and code 13. Any info would be greatly appreciated! Thanks!
