Well, I replaced the EGR Valve and put it on the OBD and it came up with these codes 22, 23, 31, 42, 63, 72 and 73.
22-MAP Sensor voltage out of spec
23-Throttle Position Sensor voltage out of spec
31-EGR Valve Position Sensor voltage out of spec
42-O2 Sensor always rich does not switch
63-Throttle Position Sensor voltage too low
72 and 73 have to do with not enough change with vacuum and throttle during Dynamic Response portion of test. I have tested the fuel pump and pressure is fine. In addition, although timing is perfect when you accelerate you get backfiring through the intake, like it is out of time.
