From what I understand, your '91 has both -- sort of. You don't really have a MAP, you have a BAP (Barometric air pressure) sensor. A BAP is exactly like a MAP except that the BAP isn't hooked up to the manifold. It is simply open to measure ambient air pressure. The MAF is the important sensor as far as driveability.
Start by going over the wiring between the BAP and the PCM, and then test the BAP.
