Pls where is Swirl Control Solenoid Valve located in Infiniti QX4

see Swirl Control Valve in a lot of threads and Auto Help posts. It is actually called a Solenoid Control Valve (14956-31U01) as Nissan diagrams and parts lists don't have anything with Swirl.

P1130 Swirl Control Valve Solenoid

on intake manifold

According to Nissan, each cylinder has a valve in the intake manifold to control the air volume in the intake. The code is for one of the swirl control valve solenoids.
Code 443 is for the EVAP canister purge volume control solenoid which is a part the computer uses to vent the gas tank.
I would recommend a shop for both codes.

P0443 INFINITI - EVAP Canister Purge Volume Control Solenoid Valve

Possible causes- EVAP control system pressure sensor
- Damage harness or connectors to the Purge Control Valve
- The valve circuit is open or shorted
- EVAP canister purge volume control solenoid valve may be faulty (The valve is stuck open)
Tech notes It's a very common problem with Infiniti vehicles. If the harness is not damaged, it's very likely that the problem is the canister purge volume control solenoid valve.
