Hi
The 91 uses a Speed Density System,
So the only thing you will have is an Air Intake Temperature sensor under the plenum above the fuel pressure regulator.
I just replaced mine in my 91, engine thought it was receiving air at -40deg!
There is a MAP sensor on the side of the plenum.
Cheers

Buy yourself a scanner and you will see data and someone will be in a better position to help you. Throwing parts at it till it gives is going to be an expensive hobby.

Do not throw parts at it, buy the scanner, pull the codes and/or look at the data it gives you, and we'll figure out what the problem is.
O2 sensor would not have caused it, likely a vac leak, but a scanner will tell us where to look.
