i will try to help. 171/174 indicates lean condition in engine. the mass air flow sensor is located in the rubber tube going to throttlebody. you can try to clean it. using mild carb cleaner safe for sensors, remove sensor from tube. spray clean the tiny wires located in the cylinder. do not touch them, they are very delicate. these engines are also notorious for leaking intake gaskets and faulty pcv valves. these will all set these 2 codes. feel free with anymore questions.

It's should be a simple remove and replace. Just make sure the engine is off. Also do not touch any of the filament wires on the sensor, just the plastic housing. Also after you install it drive the car for a little while (city speeds, cruising speeds and inbetween). That way the computer will be able to readjust its setting since it is a new sensor.
