2006 Montana SV6 Running Really Rough

For the past week or so, when first starting the van or coming to a stop, the van is running really rough. It has the 3.5 V6 engine. When I just started it earlier after driving it for a while but letting it sit for about 10 minutes, the car stalled the first two times after running for a few seconds. I had to start it and then gun the gas to stop it from stalling so I could just get the van moving.

BTW, I don't think it has anything to do with the problem, but my check engine light is on. The code reads Mass Airflow Sensor. But the check engine light has been on for months and this problem just started in the last few days.

Forget it, just figured it out. My wife has been complaining for a few weeks now but I hadn't experienced the problem. I opened the engine compartment and there was a vacuum line disconnected. Hooked it backup and it's running perfect now.

Glad you got it figured out! If I can ever assist in the future with recall questions or in working with one of our dealerships, please don't hesitate to get in touch!
