It should be along the air intake. A block box about 1 1/2" x 2 1/2" held on by 4 ? screws. Easy to replace, but kind of pricey. They make a product for cleaning them. Try that first. Do not touch the wire resistor that goes into the intake. It's delicate.

Assuming you have the V-8, though it is similar for the V-6. The MAF sensor is inside the air resonator flexhose.

Removal & Installation
CAUTION Take care when handling the MAF sensor. Do not dent, puncture, or otherwise damage the Honeycell located at the air inlet end of the MAF sensor. Do not touch the sensing elements or allow anything including cleaning solvents and lubricants to come in contact with them. Use a small amount of a non-silicone based lubricant on the air duct only, to aid in installation. Do not drop or roughly handle the MAF sensor.

- Dirty mass air flow sensor
- Dirty mass air filter
- Mass air flow sensor harness is open or shorted
- Mass air flow sensor electrical circuit poor connection

Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor.
