welcome aboard. was anything done before this happened? how many miles do you have? have you done a throttle body service? Is there a Check Engine Light?

 

45,000 roughly, and just replaced the full throttle body

 

Did you use OEM Nissan Throttle body? who installed it?

 

first pull any codes.. check wiring then do component level ohm readings and checks meaning find what wire is power and check for voltage then watch said foltage it dont fluctate etc... intermitant etc then check decive ohm reading making sure its within spec all else fails buy a new one toss it in and check if still does it then its something else
