hey guys...my Idle seems to be consistantly at 1500 rpms...car seems to be running fine...just changed the oil and air filters...tried to adjust the idle but it didnt help...when i adjusted it i unplugged the AAC sensor and when i plugged it back in the idle went back up 1500....any ideas?...id like to get the idle back down to where it was a month ago which was beautifully at 700 to 750
