Can anyone tell me what an MAF is, and where I can find it?:confused:

I have a 1996 Sedan Deville with an error code of P0174.
Thank you all for your help. :)

The Mass Airflow Sensor is the black tube bolted to the front of the throttle body, and has a wiring harness connected to it.

I had an error code of P0174, and I have replaced the O2 sensor. My car is hard to start in the morning, and it was recomended that I use electronic spray to clean out the MAF. Does this sound right to you? I would apprieciate any help. Thank you!

P0174 indicates that the left bank of the engine has an abnormally lean fuel trim based on the closed loop fuel control.

That code would not lead me to the MAF as the MAF contributes equally to both banks for fuel control.

I would start looking for a stuck injector on the left bank if I were you....
