Thanks all! So sorry for the late reply.
My '04 was in the shop for a shorted trans-temp sensor harness/sensor. While it was there I asked them to look at the EGR issue. They declared the EGR Intercooler to be leaking, but i see ZERO evidence of that. I believe it was an easy answer to my EGR question that would pay them $3100 (EGR/oil coolers). I opted out.
To my knowledge they never had any reason to check the EGR valve, yet the valve is operating perfectly now. It was chugging under throttle before I took it in.
I will probably replace my EGR intercooler with an aftermarket, such as a Bulletproof.
