Rolfe3 and Jim, yup, the code came back today and I guess I did mis-count the flashes (oops). EGR fault is what you said and what I remember being the possible problem so when the motor cools down I'm going to take the pipe down that runs from the EGR over to where it ends up and clean it out (read about plugged line while researching ) Thanks again.

Paul, I don't know what happened to your response with the pic, one minute it was there, then POOF, gone. What you had pictured is not at all like my car. Still wondering if I have an oddball car with the LED/reset plug Thanks again to you as well. (still haven't figured out how to put a pic in here)
