i need some help my car idles like crazy. the car is a 93 civic coupe with a 95 gsr swap and turbo. car is tuned on crome. it idles at 2500 when warming up then as soon as it is warm the idle jumps up and down. i have an obdo throttle body that is bored out so i have a map sensor hooked on on the firewall. there are two holes in the throttle body nothing happens when i plug up the bottom one. but when i plug the top one the idle stabilizes but stays at 2000rpm. i also have the idle screw adjusted all the way in. im almost 100percent sure that its not a vacum leak. but i guess i could be wrong any help would be great. you guys have helped out tons before hopefully you can do it again.
