Can I just say that I LUV YOU GUYS!!! I've been working on stuff and had been wondering about my EGR valave. But I just tried the above mentioned test and the car responded perfectly. I've cleared my TB/EGR ports and now am left with a CEL indicating 122 (TPS low voltage). Hopefully only $20.00 to go.
