So my idle returns really slow and also doesnt fully return. It will drop to around the 800 rpms then go up to the 1100 rpm mark then slowly go to around 950 and stay there. At normal idle with my car warmed up it will be at 800, why doesn't it fully go back? Tips guys? And also when I turn on my AC my car idles around 1300 to 1400 rpms? Whats going on there.
