I had idle issues so I cleaned the throttle body after noticing quite a lot of carbon buildup. Before cleaning the normal idle was 700, but now it idles at 950 and increases to 1050 when taken out of drive into park. I made sure not to adjust the position of the throttle plate by hand as I heard that can damage it. Instead, I got a friend to press on the accelerator whilst the ignition was on. Further, I did not remove any vacuum lines. I also tried the idle relearn procedure for the car. It seemed to help but it returned back to normal once I turned off the car. My questions are: Is this normal after cleaning the throttle body? Is it caused by additional airflow due to the lack of carbon? Will it return back to normal with time?
The car has no codes and runs perfectly find except for the high idle.
