2005 4.0L V6 - P0190, P0300 and P2198

I have multiple codes - P0190, P0300, P030x (4,5,6) P2196, and P2198.

The engine is running rich and very ragged. Stalls and sputters and then it runs fine for a few miles.

I am going to look for vacuum leaks fist. The I am thinking Fuel Pressure Sensor, then Fuel Filter, then MAF, then Fuel Pump, then drink a beer and go to bed.

I hope that I did not ruin the cats.

Any useful thoughts or thoughts in general.

Thanks for all those responses. It was the FPR. Had to take the Upper intake off to change it. Cake.
