I have this code its saying P2135 this is my first ever Z and I can’t get around what the issue could be The throttle body looks new and i cleaned it the idle is kinda high sitting at 1500 rpms any idea what i can do?

 

Most likely culprit: Throttle position sensor.You can test on car.

2nd possibility: throttle actuator

3rd: bad throttle body

Do a search for procedures. Every procedure is on here. 13+ year old car and all.😆

Just realized… my350Z is 20 years old! Happy Anniversary to us!
