Low idle vibration

So suddenly, I've noticed that I feel a strange vibration after my car warms up at idle. It seems to be idling low and if I artificially bring it just slightly higher, the vibration stops. Any ideas?

Sounds like it has a miss, could need new spark plugs, have a vacuum leak or?

mine has the same

its a very minor vibration and no one can feel/hear it but me

try the easy stuff first

try some fuel cleaner

lucas or sea foam work great

if that doesnt work, look at plugs and vacuum lines

Its MOST LIKELY a vacuum leak. the vibrations are due to low idle...low idle is due to vacuum leak normally. Could also be the throttle body or the MAF. I would put money on the vacuum though.
