Air bubbles in toilet...Vent issue?

How would you know if the vent is plugged ?
I noticed recently that the toilet somehow gets air bubbles.
It is not coming from flushing.... I flush the toilet and everything seems ok...then a few hours later I come by, lift the toilet cover and see air bubbles under the water...on the surface of the toilet....

thanks!

EDIT: for the ...hilarious spelling errors when you on auto-correct and type without reading what you've just typed

Why are you flashing the toilet, it has no eyes to even see you do it?
If it was a blocked vent it would be making a loud gurgling noise.

Funny. Actually I think we all flash the toilet each time we use it!

Seriously.

Are the air bubble active as in moving to the surface or are they clinging to the sides of the bowl? Is the water supply direct from city supply or are you going through a filter or purifier? Take a large glass of water and fill it. Let it stand for several hours. Do you see air bubble clinging to the sides of the glass?

The water has bubbles because you have a partial clog. The toilet water is trying to siphon out. This is because the partial clog is blocking the vent tie in. Normally where the sink ties into the toilet. As the water slowly drains down the line its trying to pull water from the toilet...

the sink that uses the same DWV pipe is often clogged and I only use liquid plumber which helps just a bit.... I am planning a complete remodeling in the next month - this is the only reason I haven't tried to use a snake or even open up the P-trap.
