SOURCE: having problems with my 96 chevy tahoe mass air flow
The MAF (Mass Air Flow) sensor is a very common problem with these along with the pickups. This isn't what you would call an inexpensive part. Definitely do some shopping before you buy one.
SOURCE: Cleaning the Mass Air Flow Sensor
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.

The M.A.S. is in the top of the metal tube between the air filter box and the intake manifold. It will have a wire connected to it and it is held in by 2 screws. This is an easy replacement and should take no more than 5 to 10 minutes, assuming you are taking your time.

The sensor is mounted on the throttle body between the air cleaner assembly and the air cleaner outlet tube.
