Try cleaning or replacing the idle air control valve.

Any trouble code after replacing the aforementioned parts?

Ensure the main engine harness ground points are clean. You should be able to find them by following the main engine harness and then close to the intake manifold, there should be 2 ground lugs bolted to the frame. Clean the lugs and frame and if possible, apply dielectric grease.

Verify you don't have any intake/exhaust leak. Check the air filter and the lines all the way to the throttle valve. Exhaust leak may be a bit challenging but follow the line and check for cracks loose fittings. Did you buy OEM MAF sensor? Which spark plug did you use? Bosch plugs can cause problems with Nissan/Infiniti engines.
