hi..

i have a32 nissan maxima qx..İts manual..If we come to my problem;

where we stand at any place in the city and there is no problem,but When we made the long road of 150 km or more and gas and gas loaded into the vehicle stops suddenly shuts down, then suffocated in..When it comes to three thousand revolutions gas cuts,but when it comes to going back two thousand revolutions..

Some maf sensor, potentiometer, some say, but it's very expensive if the fault potentiometer...

Can you help me please..Thank you..

 

how many km on the car?

could be MAF but could also be the catalytic converter is clogged up

 

Have the car scanned for any stored error codes.
Sounds like the MAF is failing.

 

264.500km(164,300 mil),We've previously looked into the catalytic converter with the camera, there is no problem..where we left off for repair;could not replace the throttle position sensor, nissan went to authorized service, the sensor was replaced and adjusted with the original software, but still had the same problem..The only fault that the sensor output, if it has been fixed
