I noticed the air tube going into the the fender from air cleaner is shot has rips and tears through out but otherwise what would be the cause of such a rough idle? At times the car will stall such as last night I back out of a parking spot wheels turned not full lock and it stalled started right back up though. On take off though no matter if the vechile is warmed up or not it will sputter to get going and then drive fine.I did check for vacuum leaks really didn't see any. Running a bone stock 260 v8 th350 trans AC Quadrajet 2 barrel. Any idea would be great thank you!!

Could be a bunch of issues. Start with the basics:
When was the last tuneup? Plugs, wires, cap, rotor.
What is the timing set at?
What is the idle speed set at in gear, brake set?

I find bumping the idle up about 100 rpm over stock helps. As said it could be a few things. Does it stall hot or cold?
