Default 02 ram 4.7 dropping idle and stalling out

I have a 2002 4.7 ram 1500. The truck has 20k miles on it with just flowmaster dual pipes. The problem is that when I come to a stop the idle will drop to around 400 or so and sometimes stall. This has done it before I put the exhaust on and I tryed cleaning the tb out and stuff and that didnt seem to work at all. Anyone have any ideas what could be wrong? The truck isnt throwing any codes or anything so I dont have an idea

I had the same issue with a Durango 03 SLT+..4.7l.. The left side of the engine had allot of carbon build up on the exhaust valves and was also missing 1 out of every 500 rpm's..... When you are ideling the truck I bet you can smell strong odor of exhaust/gas. Run some SeaFoam through her and see if that helps... Good Luck

Also, one thing that might be happening is a carboned up PCV valve. This will cause some driveability issues, missing, stalling, sputtering, etc. The SeaFoam may help or you might have to remove it, clean it and put it back on. Be careful of the sensor there.
