I have a 2017 lariat 5.0 and I was wondering has anyone experienced this issue I’m having. When going up a incline of any kind I notice a vibration for a few seconds when accelerating seems to do it more in 6th gear I can lock out 6th gear and it doesn’t do it, is this a shutter issue?

 

How many miles on the engine? It might be in need of a tune up.

 

If the spark plugs are good, it could be caused by weak ignition coils or that would be my wild guess. I'd start by changing the plugs or better yet, get a complete scan done with a good scan tool.

 

100k I just bought the truck a month ago

 

If those are still the original plugs at 100k, they need to be replaced.

 

Ya that’s the thing idk what has been done prior to me, a old man owned it and traveled for work until he retired

 

Wouldn't hurt to replace the plugs anyway.

 

My last truck did that when I put my foot in it. It turned out to be the plugs.

 

That is DEFINITELY a spark plug issue!! Had the same thing happen to me.

 

Ok thanks I’m going to change plugs this weekend
