Toilet
As soon as my toilet(15 yrs old)is flushed, an air bubble breaks on the surface of the water in the bowl. The toilet seems to be flushing rather sluggishly as well.
You have a partial obstruction, sometimes it's human waste and flushing several times will get rid of it. Something may have dropped in your toilet and got stuck. If snake doesn't work, you'll have to take toilet off and see what the obstruction is
The obstruction is most likely 'near' the toilet based on your symptoms. Also, look into checking your Vent Stack. It could be obstructed by a bird's nest or something. Bring a flashlight w/you up onto the roof (and BE SAFE UP THERE!) Also, check the vent in the front yard too. If there are other toilets on the same Stack, and they're OK, then the obstruction is most likely between the 2. If ALL toilets on the Stack have this problem, the obstruction is most likely in the stack (not in the drain line.)
My best to ya and hope this helps.

PS: If your sinks and such are having problems draining, see how they 'tie' together and go from there ...

I have already tried a toilet auger and found no obstructions. Which do you think I should persue first; taking the toilet off or checking the vent stack?
The air bubbles have been happening for quite some time (6 months to a year). The toilet was flushing fine during this period.
The sluggish flushing is a recent event (the last 4 weeks). I have had to use a plunger several times in the last month.
Something is choking your flow, when you plunge does that help flow or not? I have also seen things stuck in toilets where they are small enough and lodged tight enough that a snake passes right past them and one would never think anything was there. Also, check the flow holes along the inside edge of your bowl, see if they are plugged.
