After aggressive driving my truck will idle rough for a minute or so then calm down and idle smoothly again. If I drive normal it never does this. Is this a problem or a characteristic of these motors? To add detail it idles like it would during a very cold startup.

 

mine does it too when its turned up..... hmmm. i never thought to mention it. curious to see where this goes. good post man.

 

My guess would be low fuel flow/psi causing fuel system to pick up air. Does it seem to cackle more during that time as well? Other with more know will be along later but maybe this will give u a bump.

 

No more cackle just rough and sounds like I have a larger cam to a bystander.

 

Mine is stock...for now

 

I never got an answer on this. Can anyone help? Does the cross over line help?

 

I wouldn't be surprised if it wasn't a loose uvch.

 

fuel filter service, trash in tank (water, bad fuel) you shouldn't have this, so no it's not a characteristic on a stock motor.

 

Thanks. The truck came with new filters. I do not know the quality of them though. I'll try that. I buy fuel from the same place I always have and I have never had an issue in my previous truck with it. I'll check the UVCH.
