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.

Very easy for the Mass Air Flow Sensor....it is in the duct between the throttle body and the air filter box. Just unclamp the tube and remove the old and replace with the new.
On your pack....I need the engine size.

Check the wire leads and clean them before reconnecting the wire leads. It wouldn't hurt also to clean the MAF sensor with MAF cleaner, the code your getting is most common to the high performance oil base filters like K&N.
Good luck and this should help you resolve your MAF issues. Thank you for using Fixya

The mass flow sensor on the 1999 intrigue is along the intake tube right
after the air filter intake housing. Loosen the two clamps that hold the
MAF sensor between the Air filter box cover and air intake tube,
disconnect the wire leads at the MAF sensor connection and remove the
MAF. Note it's uncommon for the MAF sensor to go bad and 95% of the
time, cleaning it with MAF sensor with MAF cleaner will fix any problem
it may of had to trigger the DTC codes.
Start with trying to clean it first just by following the instruction on
the MAF cleaner. This should save you time and money to get your Intrigue
running 100% again soon.
Good luck and thank you for using Fixya.
