well my car has beem doing this for the last 2 days when i am slowing down to a stop it idles at around 1500 - 2000 and as soon as i come to a complete stop it drops to 900 like supposed to, anyone know whats going on? my setup is a skunk2 manifold with a skunk2 68mm throttlebody so nothing is adjustable

 

anybody????

 

damn, nobody knows

 

same thing happens to me

 

yo i think ur o2 sensor is going bad....try another o2 sensor from a buddy or somthing...bad o2 sensor can wont let air/fuel read properly...

 

could be vaccum leak or throttle body not closing as soon as u let of the gas. sometimes the throttle body will get all gummed up inside. pull off ur intake pipe and check it out

 

had same problem......cleaned my throttle body and adjusted the accelorator pedal, now everything is good
