I took the throttle body off and sprayed the fluid onto a rag and wiped it off. Then i moved the butterfly valve with my hand , and cleaned the area where it sits, it was filthy.

Upon starting my car for the first time, I got the infamous check engine code and surging idle from 1100 rpm to 1600 rpm. I figured that I just needed to an air idle relearn, but I wasn't that lucky.

I tried the gas pedal procedure many times and I did it correctly each time, with no luck.

I talked to one of my friends who is a tech at the Nissan dealer, and he tried to do an air idle relearn using the Consult II, and it still wouldnt take.

By this time I was getting desperate. I figured that I would have to buy a new throttly body.

I decided to try something that I saw on another website and it worked.

I started the car and drove it around until operating temperature, then parked on my driveway. I unplugged all 3 of the front fuel injectors to force the idle lower. A check engine light obviously came on, so I shut the engine off and did the ecu reset procedure. With the engine still off, I did the air idle relearn procedure. It is important that you do not turn the engine on before doing the idle relearn because it will throw a CEL due to the unplugged injectors, and the idle relearn will fail. Well wadda ya know, the idle is right at 6-- rpm.
It took the relearn.

I hooked up the 3 injectors again and did another relearn just incase, and it took fine.

So anyone who is having problems doing an air idle relearn, please try disconnecting 2 or 3 of the injectors and try the relearn again before you let the dealer rape you on the price of a new throttle body.
