Here are the most common causes of idle surge, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake

The battery is only about 2yrs old.
After I replaced the IAC Motor it ran ok until I turned on the a/c then it started cutting out. It seems like the idle is set to low, I'm trying to figure out how to adjust the idle.
Not sure, have to get the code reader back(loaned it out). But it is doing the exact same thing as before I checked the code. If I pull the pcv hose off it will run fine.(Don't know if that helps)
The battery is about a year old, I got it at Auto Zone (I think). I replaced the IAC Motor and I am still getting the same code P0505 Idle Control System Malfunction, but on the OBD reader It said P0505 and then PENDING. ???
