Low idle I just finished having my LT's with new O2 sensor extensions put in and continue to have the same issue of a low idle. Sometimes, the engine wants to quit but it "catches" itself and brings idle back to around 700rpm. I just got a mail order tune and I drove it around the block when the issue started again. Can it possibly be any other problem?

Sounds like this was happening before the mods?
Could be many things but I would first clean your throttle body and TB blade edges, inspect/clean IAC.
Those are free and relatively easy to do.

Ok, I'll try that. I didn't replace my o2s, just bought extensors, to clarify. If it is my o2 sensors going out, are they relatively easy to remove and replace?

I forgot to mention, I have an A4 and whenever I put in in reverse, park or drive, the drop in rpm's seems more dramatic for a second. Don't know if that narrows my problem or not.
