Surging / Fast Idle....
Just this past week my car has developed an idle issue.
When it gets warm it will surge a bit when stopped at a light.....idle will go as low as 600 and as high as 900. Never feels like it's gonna die.....idle just goes up and down. Also.....when I decelerate from the freeway to a stop of the off ramp, the car will initially idle at about 1100, then after 5-10 seconds will slow down to the correct idle.....then start with the surge thing again.
There are no codes........any suggestions?

I checked all my vacuum lines.....found a tear in the brake booster grommet. Replaced it and the car idles smooth as silk!
I was convinced it was gonna be some spendy sensor or something.....but nope....all of $1.99 fixed it!!!
Thanks for the suggestion!

I am having some surging/hesitation as well... Anyone have a list of vacuum lines? I may do a total swap, I just patched one do to a battery leak but this seams to be a recurring issue lately here on the forum...
