hey wats up h-t. i just got a sohc vtec in my coupe. it runs perfect, it starts up every time and theres no check engine lights. for some reason though ill start to like pull up or sumtin and wen i let off the gas and go for the brake it revs up a little every once in a while when i just start it. every once in a while it will like a rev up and then stop and do it a couple times. now i noticed it does it when its cold and my dad said it coould also be the vacume lines that are not hooked up. any help would be great thanx.
