1991 maximaa
1991 maxima with 64k-car ran great until a few weeks ago-while driving on the highway at 60-65 mph it just loses power down to an idle but won't stall out-it idles rough and while pressing the gas pedal it will not rpm over 1000-after a minute or so it runs great again
I've replaced the rotor,cap, wires, plugs,fuel filter and pump and cleaned the mass air sensor
Could it be the air injection valve(or what) ?

RE: 1991 maximaa
Check the o2 sensor to see if the voltage is outside parameters when incident occurs. Does this happen after climbing an incline. If so it is possibly the 02 sensor. It may also be the Mass airflow sensor. Check the voltage drop across the ground side of the sensor. If more than .2 attach a new ground wire to reduce the voltage loss.
