i have noo clue what this is

my car idle high and when ti drops down it jumps up and down from 1000 to 1500

does any one kno how to fix this???

 

doent really sound like the atmospheric pressure sensor. that sounds like ur idle air control valve which is located on the back of ur intake manifold. so what year integra do u have?. and btw the atmospheric pressure sensor is located inside the ecu so maybe u should swap out ecu just so you can start trouble shooting your problem. Check for any vaccum leaks also in and around the intake manifold and the throttle body.

 

sounds like some sort of vacuum leak to me.
