i have a 96 automatic civic 4dr and when i start the car and when its cold it idles high just like any other cold start idle.....and when it warms up and wants to idle down it goes into a mode where it idles up and down and up and down.....but when the air compressor kicks on it dosent bounce just stays high...... when i turn the air off its goes back to bouncing up and down.....what could this be?
