My mom’s stock '03 nissan sentra spec v is throwing a PO507 code. Car has 40000 miles on it.

Throttle body has never been touched, as when googled the problem was generally a person cleaning the throttle body and damaging it.

It idles at 900rpm, which is normal. When AC is turned on it fluctuates btw 900-1100 and goes back to 900 idle.

When releasing the throttle the rpm floats then drops quickly.  
Any ideas?  
Thanks Mike

try this…its a common issue i guess

Idle Relearn

This seems to be a pretty common thing if you swap tbs or clean your tb. Here is how you do it.

-Warm up engine.  
-Turn ignition switch ?OFF? and wait at least 10 seconds.  
-Confirm that accelerator pedal is fully released, turn ignition switch ?ON? and wait 3 seconds.  
-Repeat the following procedure quickly five times within 5 seconds.  
a. Fully depress the accelerator pedal.  
b. Fully release the accelerator pedal.  
-Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the MIL stops  
blinking and turned ON.  
-Fully release the accelerator pedal within 3 seconds after the MIL goes ON.  
-Start engine and let it idle.  
-Wait 20 seconds.
