Where is the MAF sensor located on a 1991 Chevy 454 7.4?
The 1991 Chevy 454 7.4 engine does not have a Mass Air Flow (MAF) sensor. Instead, it uses a Manifold Absolute Pressure (MAP) sensor to measure the pressure in the intake manifold. The MAP sensor is located on the passenger side of the engine, just behind the throttle body.
