Ok I have a toilet that Flushes REALLY slow and after the bowl emptys massive air buibbles come back into the bowl. I have of course plunged,checked the jets, cleaned with CLR and tried Liq Gel Draino with no change. The tank fills just fine but that's about it.

Thanks in advance for help:cool:

Is this a downstairs toilet?

If the drain pipe to which it is attached is "small" (three inch rather than four inch) or partially plugged or insufficiently graded, a small air pocket can form immediately in front of the oncoming waste and water.

The bubble will follow the path of least resistance.
If it requires more pressure to continue down the line than is required to escape through the branch line to the downstairs toilet, the downstairs toilet will "burp", especially if it is not vented seperataly from the main vent, or if its' vent is plugged or partially plugged.

First try cleaning the line. Do it right, with a proper size blade or spud running well out of the house. If that doesn't solve the problem, investigate the vent.

Single story home has been used for many months without problem... and can't seem to find/remove a blockage

Did you rod the line, and vent?

Have you used one of these on the toilet?

You have most likely ongoing cloggage in progress. This is a warning to have your sewer cleaned.

I do not necessarily agree with the comment that 3" line is too small. In my area of operation, 3" line is up to Code and widely used without problems.

I would remove the toilet and snake the sewer through the Closet Ring opening.

I agree with Milo, Bubbles indicate a partial blockage.
A 3" branch is acceptable for a bathroom group in my area. The best place to snake is from a pulled toilet but be advised that there are several other ways to get your snake into that branch.
1 You can snake from the lavatory roof vent , **OR**
2) you can remove the tub waste and over flow and snake from there.
But Milos way will lbe the surest. Good luck, Tom
