losing power

[sballan]

My 2013 ford sho is losing speed uphill and showing code p0172,p0175 any ideas how to solve this problem.

Both are system too rich codes. Either dumping fuel or not burning it. Need a lot more info to be able to help.

mileage, maintenance history, driving conditions?

since codes are on both banks, look upstream for common factors first like air filter, map sensors, purge valve, etc. still could be sensors as they age out, but let's eliminate the easy ones first.

injectors are known to develop leaks on this platform. pulling plugs will help verify.

P0175 - System Too Rich (Bank 2)

Description: ​

See the description for DTC P0172​

P0172 - System Too Rich (Bank 1)

Description: ​	The adaptive fuel strategy continuously monitors the fuel delivery hardware. The test fails when the adaptive fuel tables reach a lean calibrated limit. Refer to Section 1, Powertrain Control Software Fuel Trim for more information.​
Possible Causes: ​	Fuel System: Leaking fuel injectors Fuel return line restricted Fuel rail pressure (FRP) sensor bias EVAP purge valve is leaking when the canister is full Base Engine: Engine oil contamination Intake Air System: Damaged or contaminated mass air flow (MAF) sensor

This engine does not have a Mass Air Flow (MAF) sensor. It uses 2 Manifold Absolute Pressure (MAP) sensors. One is before the throttle body, one is on top of the intake manifold. Also, no fuel return line.
