i recently purchased a 93 civic and it has a weird idleing problem and i have never owned a honda so i was hoping someone here could help me. the car has the 1.5L. when i start it it idles fine for about 2 seconds then it idles high then it goes back down then it goes back up and it continues to do this. it doesnt matter if the car is cold or warm. the surge is always the same and is very consistant. i have checked for vaccum leaks and everything seems to be good there. so now im lost. i need some help. also i noticed that it has a cheapy ram air iintake off ebay and i was wondering if anyone has had a problem with those. i dont have the stock intake so i dont have a way of testing that theory but i was wondering if anyone else has had problem with ebay intakes. thanks
