1994 pathfinder power/stall problem

my 94 pathy has had a decrease in power with a rough idle. I thought it may be clogged injectors or fuel filter so I have replaced it and added a can of bk injector cleaner to the last tank of gas. It seems better but still is not consistant. Any ideas? Timing belt has allready been replaced also.

I been going through the same thing with my 95.
Change your air filter and your oxygen sensor. This sounds like it would be the O2 sensor.

Try the wire right by the air filter move it around see if the idle pick up if so go to junk yard get another one dosen't matter what make the car is as long as the connecter is the same I think the wire s are black& white

plugs?

Check out you Mass Air Flow Meter & the harness connected to it, wiggle it around. This located between yor air filter & your throttle body.
