Nissan Repair: 1993 Sentra XE, fuel pressure gauge, mass airflow sensors

Question
I have a '93 sentra XE and whenever I drive it, it doesnt accelerate properly. It is very sluggish and I put some fuel injector cleaner in it but that didnt help much. Im not sure what else it could be.

Christian,

A tuneup with new plugs to make sure they are in good order.  Also, check for codes and correct any problem.  A big deal on the Sentra is they tend to go through mass airflow sensors.  So, get a Haynes Manual and a volt/ohm meter and follow the directions in the book on how to check the mass airflow sensor.  Basically, there are values in the book and you use the volt/ ohm meter to check and see if it is working properly.  Other causes could be the throttle position switch or even a plugged fuel filter.  You did not say if you checked the fuel pressure?  There is a pressure port on the fuel rail and it is just like screwing on a valve stem cap with a fuel pressure gauge.
