This problem after only spray clean

I solved with uprev and my tuner. My tuner after many tests called Uprev and they, with teamviewer, don't understood the problem.
At the end of story i'm going, 'till 1600/1700 rpm, lean (19/20) and the problem almost disappeared.
I called also in nissan... They wanted to change me tbs and unit... More than 3000.00€

Instead of making my own thread for this, I will use this one.

Last week I installed a Kinetix velocity intake manifold on my Z. While I was swapping it over I thought I would be proactive and clean the throttle body. That was clearly a mistake.

After the install, my RPMs would hang in between shifts and idle was around 1400rpm. I also did not experience a major loss in power like others. I tried the pedal reset and a friend has an auto shop and he attempted to use a SnapOn Solus Ultra scanner to reset the idle volume. That process helped a little but still had an SES light.

So I decided to swap my brothers g35 throttle body onto my Z tonight. Its driving much better now, but I still have the SES light after resetting it twice. Ive done the "pedal dance" idle volume reset but that hasn't corrected the light. Anybody know why the light may still be here even though its a perfectly functional throttle body? Do I need to go to a dealer and have them use Consult or will my friends SnapOn work?

the light wont clear on its own. The snap on scanner or any other will clear the light.

Ive done it multiple times, I clean my TBs about once a year. Done it on my DE and on my HR. Unlplug batt, drain system, unplug and remove TBs.

clean, scrub, touch the butterfly, use a toothbruch, whatever.

Plug them back in, rehook the battery, and do the throttle position relearn.

Let it warm up and do the idle air relearn and its fine, everytime.

A lot of people dont realize how dangerous voltage spikes can be. Always disconnect the battery if you plan on disconnecting sensors and working on the car. I probably wouldnt risk moving the butterfly on its own, can clean the throttle body enough without it.
