hmmm, try lookin on your air intake tubing, or on the intake manifold.
Normally it is 2 wires connect to the sensor. I dont know where exactly but
it should be in one of those spots.
The '91's manual shows it in the front-most runner of the intake manifold,
just behind the timing belt. It's round, held in by two Phillips screws,
and sits on a slight angle.
