On my 3rd day after resetting the battery /ECU, My EGR I/M is now complete and OK. Iwas also informed that the EGR valve doesn't really kic in until the higher rpm range. The egr valve does have the DPFE sensor and solenoid pump. My hesitation is basically between 1600- 2000 Rpms at it's worst and may have a surge issue at cruising speeds under light acceleration. I can alsways throw another 50 bucks at it and replace the EGR valve. its been a 2 month troubleshooting process
