I got it to work!
I didn't know you had to be on the lifetime section of the FCD, then press "trip" to switch between A and B but it works just fine! I also Filled up the tank again now with a perfectly running car! EGR plate cleaned, EGR replaced, oil change, brand new tires. This next tank should be good! the last tank I mustered 47.7 at 456 miles which is way better then 41.5 and 324 miles. Now everything is fixed, EGR plate cleaned, EGR replaced, all fluids serviced, brand new RE92 tires, and 89 of full tank, the last 2 tanks I used Medium grade gas so we'll see how 89 does.
