Steeringwheel cold start

Trying to find what I thought was the tsb, condition: on cold start, slight vibration through steering wheel with a short hum,

Thought it had something to do with something being possibly overtightened. Read thru tsbs but couldn't find it. Thanks

There was a thread on this back in 2011....

Upon further thought, you might have an engine mount going bad, or possibly a dirty throttle body causing a rough/lumpy idle when the engine is dead cold.

My thoughts precisely, a dirty filthy TB , can cause that shake in' all over feeling when cold.
That's why I give mine a cleaning every Oct 1 or as soon as to get ready for the onslaught of winter.
