87 ranger 2.9 running rough

I dont have a CEL but I ran the scan tool "KOEO Memory code" and got code 31 "EGR Valve position or exhaust pressure transducer sensor voltage low" What is this?..a new o2 sensor needed? I have pacesetter headers and I had to plug up the EGR if I remember correctly. Any ideas???

your ranger has an egr position sensor. its about $30 if i recall correctly. with you plugging the egr up, its probably throwing a code

Well today I changed the fuel filter, plug wires and still get a rough idle at Park and it wants to stall when in reverse at low speeds...when I put in in drive and just drive it....it seems fine. So I am out of ideas of what it could be..? I checked all vacum lines...
