Jeep Information

I have an 05 TJ with under 80,000 miles on it. I modified the exhaust so it’s a cat-back dual exhaust now. I have the pipes leading out in front of the rear tires (looks and sounds pretty cool). Anyways, other than that I have no other mods on it yet. Recently, the Jeep has started idling rough, as well as, acting like it will stall when slowing to a stop or accelerating from a stop. I’ve cleaned the Throttle Position sensor & the throttle body, changed out all spark plugs, installed a new rail with no change. I added SeaFoam to the tank and got immediate results for a few days. Then the rough idle resurfaced. So, I added SeaFoam again and so far no change. Any ideas?
