sounds like either the intake air temp sensor or the Mass air flow sensor.
both will lean out the fuel on bank 1. Bill has it right. I know that
Advance auto parts will do a read for free and print the results for you,
Autozone is also supposedly capable of doing a read. The temp sensor is
about $10 to $15, The MAF is just over $100. It is also possible to have the
MAF cleaned or rebuilt in some cases. All cars made after 95 are able to
have the trouble codes read. good luck

Up here the MAF is over $300 (assuming V6, if you have 2 banks).
I just replaced one and it did not solve my problem - lean code at
idle both banks (long term fuel trim 25 at idle) - no stalling.
I have had a succession of leaks - starting with manifold gaskets -
and also had the water pump go.
Today I found a leak in the bottom of a vacuum hose (chased it down
with a stethoscope after it got bad enough I could hear it hiss) and
my LTFT at idle now below 20 and dropping)
Check EVERY vacuum line on the ngine - and then CHECK THEM ALL AGAIN
before blaming anything electrical or electronic for the problem. One
thing Ford has repeatedly been unable to manufacture or sourse is
decent rubber hoses.
