swaped a b16a2 OBD2 into my 98 civic HX. all is well with the car. car runs great but it seems that when you come to a stop sign after driving the idle stays up around 2.5 to 3000 rpm's for a few seconds before dropping back down to normal. no codes and no other issues with the drivability of the car. Could it be a vacuum leak in the intake or something? its got me puzzled. need help. its nothing simple like throttle linking or anything. all possible quick fixes have been exhausted. and it has a wierd idle pattern when ou first start it when its "cold" i guess you could say. flexes and almost sputters at you. you flip the throttle and it goes away. maybe these are ties in together? HELP! This is Racking my brain! Yea its a minor problem but its annoying. lol
