Codes are..
a- P1127 = Long Term Fuel Trim mult.,Bank1 System too Rich.

c- P1141 = Load Calculation Cross Check Range / Performance.
These refer to a fuel air mixture issue, (a,b), and a Mass Air Flow, (MAF), sensor problem, (c).
code p 0035 refers to heated oxygen sensor(HO2S)--LH front ---heater circuit malfunction===causes ---wiring--HO2S--air induction system---fuel pressure ----injector/s---ECM
heated oxygen sensors are always located in the exhaust manifold/pipe before the cat converter
they control the fuel/air ratio parameters for the ECM to get best burn of the mixture
Oxygen sensor (O2) is always after the cat converter and sets the parameters for the cat burn off
This error indicates a failure of his sensor which provided the problem is not caused by bad wiring will need to be replaced. The sensor itself is located in the exhaust manifold near the center.
Cost of the part from a dealer is around $200.

Code p1131 manufacturer control fuel air metering, on a 2003 Ford Taurus. Where is part? Is there an easy way to see if it can be fixed without buying the expensive part?
the other areas the fault could be located are in your meter circuit plate (which is part of your combination meter), it could be in the wiring, or possibly your multi display (also part of your combination meter)
