this is for a friend his car idles at 1k warm. but say if he revs up to 2k revs as its coming down wil be fine then it will get to 1.2 for a sec then 1.1 then 1.0 then stays at 1k revs it doesnt fluctuate once its at 1k its perfect. just when it goes down. its not a problem. runs mint. i think his dv is lecking air but i dont think this would cause the problem does anyone have any ideas? thanks for any info given ps i have cleaned the icv
