Thanks for the reply Chris. I'm not exactly sure how, but I got the EGR readiness monitor back to ready-state this morning and suspect your theory is correct re: MAF deviation. Between a combination of cleaning the EGR valve, cleaning the MAF sensor (which I had not done since...oh, never), fixing a vacuum leak, thinking about it from 1:30am to 4am and then following the drive cycle instructions closely, my monitor is actively running again. Hopefully it will last until the smog shop opens on Monday. I appreciate the response and insight. Respectfully, Td.
