Car stalling when idling, AOS or Vacuumn Leak?

Recently my car has been stalling when it idles (in neutral or when the clutch pedal is pressed), I got codes for MAF and Oxygen Sensors so I replaced the Oxygen Sensors and cleaned the MAF with a cleaner from the auto store.

The car runs much more smoothly now, definite increase in power and the idle is much smoother WHEN IT IDLES. The problem is, half the time when I let it idle at a stoplight it will stall, but it starts again immediately. I noticed one time I was running the AC on idle, but then felt cold so I turned it off. Upon turning the AC off it did stall instantly, but again started immediately.

Could this be a vacuum leak? AOS fault? Maybe the MAF needs to be replaced?

If it is a Vacuum leak or AOS, are these easy DIY fixes or should I send it off to a mechanic? I'm still quite a novice when it comes to mechanics but I do know my way around.
