P0507 High idle help

It does put increased wear on transmission components from shifting park-drive with the rpm's elevated but it should be fine for a little while. It's possible you damaged one of the TB's while cleaning it, especially if you were manually opening the butterfly valve. The actuator motors are incredibly weak and not designed to be essentially "backwards driven" by having the large TB gear turn the small drive motor worm gear and I typically don't move motor-driven-throttle plates because of that.
The problem however is likely that it still needs the idle air recalibration done. Where EXACTLY in the steps are you having problems?
Idle Air Volume Learning (Throttle Position Learning)
It is better to count the time accurately with a clock.
1. Perform “Accelerator Pedal Released Position Learning”.
2. Perform “Throttle Valve Closed Position Learning”.
3. Start engine and warm it up to normal operating temperature.
4. Turn ignition switch “OFF” and wait at least 10 seconds.
5. Confirm that the accelerator pedal is fully released, then turn ignition switch “ON” and wait 3 seconds.
6. Repeat the following (steps 7a, 7b) procedures quickly five times within 5 seconds.
7a. Fully depress the accelerator pedal (HARD)
7b. Fully release the accelerator pedal.
8. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the Check Engine Light (CEL) stops blinking and turned ON.
9. Fully release the accelerator pedal within 3 seconds after the CEL is ON.
10. Start engine and let it idle.
11. Wait 20 seconds.
12. Rev up the engine two or three times and make sure the idle speed and ignition timing are within the specifications.
You MUST use a stopwatch to count time accurately.

Yeah mine does a lot of strange things ever since I cleaned the TB's. If I turn off the AC it also starts "hunting". Sucks these cars are so sensitive.

If you have an android device and a bluetooth OBD2 connector you can use the app Nissan Datascan 2, I'm not sure if the LITE version also supports but the full version (like $8 on the play store) has a button for resetting the ECU and idle air. I just verified by resetting mine with the full paid version.
This is not the full PC version of NDS2, just the phone app.

Ahh yeah forgot you have an HR, yes you need NDS3
I use this OBD2 adapter, worked well on every vehicle I've hooked it up to.

The VQ35DE was used on vehicles from 2003-2007, there were two variants of the engine, the first had only intake cam timing advance and the second had both intake and exhaust and was called the "rev-up" motor. The rev-up was used only on 6MT equipped vehicles from 2005-2007. 2007-2009 sedans and 2007-2008 coupes came equipped with the VQ35HR which is identifiable from the twin intakes. 2008-present coupes and 2009-present sedans were equipped with the VQ37VHR and the chassis was name changed from the G35 to the G37 (and later Q50/Q60).

Will do that. I read to try the lite version before purchasing it to confirm compatibility. How do you tell that my vehicle is HR ? Thanks for all your help I will order the OBD2 reader that you suggested and hope this will fix it.

Because your vehicle is a 2007 and AWD, that configuration was only available with an automatic transmission hence the HR motor, you can verify this yourself by looking at the VECI label inside the engine compartment. That's the emissions control sticker and it will include things like chassis style, paint code, and the engine class, it should be stamped VQ35HR on the engine class. You will also have two intake tubes coming off the motor to two separate air filter boxes on either side of the grill. You might be able to do the resets with the lite version, I've never used it before so I don't know.

Got the Bluetooth OBD reader that you suggested. The LITE version of the app let me do the idle relearn so that you can let other people know for future references that it does work with the lite version. After doing the idle relearn my car now idles at 650 RPM not sure if that is normal or bad I've read that it is supposed to idle at 850, at least its not idling at 1100 anymore. Another thing I've noticed that after doing the idle relearn, when I floor it the A/C seems to turn off for a second or two.?
