1991 5.0 missing running rough and oil loss
List
I have a 1991 4x4 5.0 with an E4OD transmission 115,000 +_ miles. The truck has a miss that has gotten worse. I have changed plugs , wires rotor and cap. In addition I have replaced the vacuum reservoir that was shot, cleaned the throttle body , changed the fuel filter etc. I have had the codes pulled and I have got the following : 328,(EGR ) evap voltage, 332 EGR not opening, 542, Fuel pump ground and 634 Manual Lever Position Sensor. In addition to the missing I have found oil in the air cleaner, I replaced the PCV valve with a Motorcraft one when i discovered the oil issue. My question is this is the ERG issue causing both the missing and the oil in the air cleaner issues? or do I have more than one thing going one? I have the correct voltage ( 5.0) at the EGR sensor but I have not been able to test the sensor yet.
Any guidance would be appreciated.
Thanks
