Deteriorating Gas milage - could it be EGR related?
My EGR had been pooched for a while (i'm out of warranty and wasn't motivated enough to take on unclogging the intake myself) so i've jusrt been resetting the CEL with my hand held scanner about once every 2 weeks.
I used to get roughly 400kms to a tank which it itself is horrible but I just barely got 350 out of my last 2 tanks.
I've recently done new NGK irridum plugs and cap and rotor, the wires apear in good shape and the car seems to run fine.
The only think I can think of is a new o2 sensor or the egr causing problems. Any thoughts?

Blocked EGR did not affect performance on my Accords (2.2L) which I drove for some time before clearing the EGR ports and manifold. No change in gas mileage. I finally was pushed because I was close to failing the NOX emissions test in TX.
An O2 sensor will affect gas mileage, but it could be other things. Tire inflation, inlet air filter, catalytic converter partially blocked, or dragging brake pads. I would check all these.
good luck
