EGR blocked off, can EGR ports still be a problem?

i have egr and fitv blocked off without problems. what brand o2 sensor did you get? if it's anything other than denso or ngk/ntk that could be the reason for low mpg

Actually it was getting good mileage at first, the plugs got fouled with a few times and probably just need to be replaced. Code 43 disappeared when I reset the ECU

The FITV has no connection with the ECU, its only modifier is coolant temp so no CEL there. I had my FITV blocked off, and the only real difference was no high idle while the car is warming up. Not the greatest idea in a cold climate.

The IACV can be blocked off, but the valve itself must be left plugged in or the engine will be in limp mode with code 14.

Yah, I didn't think the code 14 would actually give you limp mode. That's the crappy thing about fuel injection.
