I was at a drive thru today waiting and suddenly my car turned off. It started up right away however. Here’s what happened before that incident.

- Camshaft sensor (passenger side has been replaced)
- MAF sensor has been replaced)
- had SES light come on because of camshaft sensor (passenger side)

Car idles at 600 RPMS when it’s at its operating temperature.

Am I supposed to do the ECU reset when I change the sensors or? Has anyone had this issue? Or know what causes this issue?

2004 G35 Coupe Automatic (yeah I know)

 

Did you use OEM or Hitachi cam sensors?
These cars don't play well with aftermarket sensors.

 

Yes, the cam sensor I bought was an OEM Nissan sensor that I bought from Z1.

 

Sounds like you need to do the idle air volume recalibration, steps are in the service manual section EC - Engine Controls at the front under "basic service procedures".
