Looks like everybody a something diffrent to say. really when it comes down to it. if other tundra owners are not talking about it. You need to take it in to have it worked on. It could be so many things. To pin point it to a part without hearing it in person is impossible. Remember that these engines have alot of aluminum and can shrink when cold. Thats why is gets better when the engine warms up.
