I have a 2003 Explorer 4.6, about 2 weeks ago the CEL kicked on but I didn't notice any problem. Last week I stopped at a red light and felt it shacking a little, I took off everything seem ok. At the next light I felt it again and that time it started sputtering, I drove it for a few more days and it would sputter now and then as I was driving and every time when I would stop when it was in drive. I had the codes pulled and it came back with P2196 & P0405 (o2 & EGR). I was going to buy a new 02 sensor & EGR but I was told that a bad EGR could be causing the o2 code also. I put the new EGR on yesterday and had the codes cleared. I test drove it for about 10 miles with no problems. Today while driving I felt it start doing it again and about 5 mins. later the CEL was back on. I got the codes and again its P2196 & P0405, Should I have changed the 02 sensor instead or does anyone have any idea what I should do next?

You need to check the DPFE solenoid. Or the throttle body neck/ riser that connects to the engines manifold . It needs to come off and there are 2 very little holes where the EGR passage is they get carboned up and clog. Also check behind the manifold where the PCV valve line connects follow it from the PCV up to the end and you will find a rubber 90 that is likely over time to crack.
