When I first got my car I decided to tune it up and cleaned the TB with carb cleaner. My high idle was then fixed by installing a new throttle body. The dealer wanted 800.00 for a new one. I was able to buy one from a guy I know. If anyone needs a throttle body let me know and I can get them a deal on one. What a relief to finally get rid of my high idle. I guess I'll never clean my TB again.

 

when you say high idle can you eleborate a bit. cuase when i start the car it initially idles as 1500rpms and then gradually it goes down, i have an auto by the way.

 

that's fine...normal for it to be high when you first start then it goes down as the car warms up.

 

couldn't you have just replaced the iacv?

 

Carb cleaner is not Nissan throttle body friendly. A lot of people would have been able to give you advice on that. They make TB cleaner that is safe for the sensors that were probably ruined in your first TB. I've use TB cleaner and it works great and safe.

 

Cleaning my TB gave me high idle and RPM surging when I was stopped at a light or something. I got my 60k maitenance done at a shop I always go to and the surging and idling stopped. Not sure what fixed it but I'm glad the problem is gone.
