I have a 2006 wrangler rubicon 4.0 6cyl 6 spd manual. When starting off the rpms go up to 3000-3500 before ive went 10 ft. I think i can hear air hissing under hoo but have looked a million times for a vacuum leak. Also have noticed the oil gauge not moving sometimes. Like if i get up to 60mph the oil gauhe is dead center. I can feel like on highway when the jeep seems to "wake-up" and run correct but tgen just doesnt. I am running stock size wheels no lift. And yes i do hate it just as much as all of you do. Any help would be appreciated. Thank you
