2012 Terrain 2.4L Rough Start and Stall

Hey guys and gals,

I have a 2012 Terrain SLE With the 2.4 with 90K miles. In the last year i have had to replace the Converter and the 02 Sensor. For the last 6 months when started from a long sit it will run rough and stall out. Normally it will stall out again when restarted. After the third time it runs smooth with no problems until its sit for 1 hour or more. It burning hardly any oil, from what i have been tracking, even though the Cat was clogged. The dealer ship cannot replicate the problem. My local mechanic has replaced the Throttle Body, Spark Plugs, MAF, both Cam Shaft Actuators, and did tested oil and fuel pressure. At this point it is still doing it and we are all stumped. I have read through multiple posts but no one ever posts what the final fix was. I could use some help here. Thanks
