Greetings,

New forum member - first post.

Just took delivery of my new ('11) Tundra. My first Tundra. Great truck, but I'm noticing a very slightly rough idle (when in Park or Neutral). Nothing severe about this rough idle (and hasn't thrown any OBD codes which would come up in a scan) - just a barely noticeable little shudder every couple of seconds (like slight mis-fires). Curious if other 4.6 owners have detected anything similar to this.

Thank you.

Bad gas, buy premium. JK

I notice something like that on my older (2006) 4.7. Every so often at random it starts shivering. I read brief clips about connections around the coils / plugs being flaky.

My 2010 4.6 purrs like a kitten.

You might want to throw a can of Seafoam in the tank and see if that helps.

I also took delivery of a 2011 Tundra with the 4.6 engine. I have not noticed or feel any rough idle at all. I have approximately 1,000 miles on it so far. Runs very smooth.

Smooth as silk here, too.

Thanks for the feedback everyone. Will bring it to the attention of the dealer at the 5K maint. visit. Thank you again.
