vibration at idle

I have a 1998 f150 4.2 auto.It has a vibration when it's in drive at an idle.You can feel it on the steering wheel,the door panels and seat.And I can't hear any noise.
Can anybody help me?

Is it just a low idle? If it's just a low idle you might wanna check out your IAC (Idle Air Control) sensor. Search for "IAC" in the forums and you'll find tons of info on it.

A good tune up done lately? Motor mount broken?

The complete tune-up is one year old.I will check the motor mounts.I haven't cleaned the air intake because there is a sticker inside the throttle body that says not to use any solvents to clean it.
what should I do ?
