Truck shaking

Hello, I can't figure out what's going on. I'm about to go to a mechanic but really don't want to fork out the amount I know it's going to cost if it's something I can fix myself. If it's transmission then I'll take it in. Basically the truck runs great but when I can only give it a little bit of gas (ie stuck behind a slow driver at a light or stuck in traffic) then the truck shakes like crazy. So long as I can push my gas pedal 40+% or so and get decent acceleration then the truck drives great. Soon as I have to just barely give it gas then it shakes like crazy. I've replaced my spark plugs and struts and shocks already. Thanks for any help

 

Any codes? If you don’t have a code reader you should be able to have an auto parts store see if there are any codes causing your symptoms.

 

Not a single code popping up

 

4 Cylinder? Automatic? 2wd?

 

I would check your carrier bearing.

Sounds a lot like torque converter shudder. I would have our fluid level checked.

 

BTW, what year and how many miles on your truck?

 

6 cyl, 2wd, 2016 w/ 260k miles

 

Personally thinking it is the flap that is inside the intake manifold. Don't know how old your truck is. But this sounds like previous cases, where the flap had come apart.

 

It is cold outside are you sure it's not shivering?

 

Center bearing or pole vault that bich.

 

One more thing to check might be U-joints.

 

Truck on idle shake crazy, can you go highway speeds get vibration?

 

Usually throws a code for that

 

Throttle position sensor going bad?
