QX4 CUTS OFF WHEN IDLE

[c0de_cipher]

Hey Team,

I am having an issue with my QX4 the "Service Engine Soon"light came on and it started cutting of when idle or when going extremely slow. I have read some post that talks about cleaning the MAF. It is currently at the Nissan service guys in my country but have any one of you experience this problem? Was this the part that is causing this cut over wen idle issue. I also told him to clean the IAC also but some guy i met told me that this problem might be an electrical problem with a sensor on the engine. Have you guys heard of this sensor? I have not been able to locate the full diagram for the engine to better help troubleshoot. I had another Nissan guy that said the fuel pressure regulator could also be causing this cut off. My QX4 is consuming alot more gas because of this issue, I did a scan with an auto scanner tool and got the codes but i am unable to upload them because i left the sheet at the home garage. There was also a code that mentioned the 02 sensor which is the oxygen sensor, i am not sure if that is problem or if that is where the problem starts. Any ideas guys? there is not more that can stress a guy than a QX with issues.lol..Please advice..>i will upload the codes for any one that gives this a read an want to drop me a line. .Thanks..

could be alot of things. like my pathfinder, I had scan with my obdII tool and got 02 sensor problems ,but I had nissan scan for me also for a fee of course and they told me fuel pressure and regulator. so dont always trust your scanner use it as a guide dont always assume that the code is right either.

Have the codes pulled by an auto parts store (AutoZone does it for free) and list them here.
