So buy a used one for $100 and swap it yourself. There are several for sale over on eBay.

Not the right ones on e-bay. But I did find a used one, and they will install and program it at the local dealer.
Total looks to be about $500.
Beats the 1300...
Thanks for all of the help and support

Got this all done and it is running good. But MPG has gone down, and getting a too rich code, but nothing else....
Any ideas? The computer was the correct one, and installed by the local Ford dealer.

Could be a dirty MAF. Or a vacuum hose disconnected from the fuel pressure regulator (or does the 4.6 in 2003 have a "returnless" fuel system?).

Looked at the code again, and it is only bank 2 running rich. This is drivers side correct?
During all of this work I did change the #2 plug to a different brand. could that cause this? It is a NGK platinum that has a fine wire, and the rest were bosch platinum. That is the only plug I removed. Did remove a coil on the other side, #6 for some testing, but never removed the plug.
So does this remove the MAF and IAC etc because it is just the one side?
Could it be the used computer? I got to get it fixed the MPG went from bad to sucks big time...
Thanks
(should this be a different post? I thought it best to keep it with the background)

Yes.

If by "this", you mean making bank2 to run rich, I doubt it.

Probably, but i'd like to see you display the LTFT for each bank. Your bank1 could be just a wisker away from tripping the P0175 code, or bank1 might be running normal at +/- 5% LTFT. Additionally, looking at the freeze frame data would give an indication if the P0172 happens at idle, part throttle, or heavy loads.

It might be worth the effort to swap the injectors between bank1 and bank2 to see if the problem follows. Its hard to imagine that all the bank2 injectors started to leak at the same time, but, who knows.

I am so tired of this, but the wife loves the car, and it has been a good car. 178K on it, other than a fuel pump, it has not been a problem. So I have to fix it.
I got back from taking my kids to college (in a different car), and the car is having more codes now.
P0175 P0300 p0511 and p0308

I pulled Freeze frame data from one code, but do not remember which it was.
Here is the data..
Fuel System 1 ok
FS2 Fault
Calc load 60.78
ETC 179
STFTB1 3.13
LTFTB1 -26.56
STFTB2 -100.00
LTFTB2 -26.56
Park adv -64
IAT 40
MAF 0

The car misses worse cold. and at one point it was like it shut off then restarted going down the road, a big jerk, then continued running.
The computer fixed the #2 issue, but I believe that these are the other issues that seemed to go away when working on the persistent #2 issue
Thanks for all the help you can give.
