egr??? i had that problem with my accord, I had new plugs, wires, fuel filter, new o2's, cap & rotor and pcv valve ans was still getting 18-22 mpg. Some one told be to see if they were clog but i never got around to do it. I just sold it but i think the new owner is going to clean them. The f22 is bad for this
