I had a problem with my idle awhile back with it jumping from about 650 to about 1500 rpm's and then dropping back down, it would do it repeatedly and I was trying to figure it out so I pulled the plug off the eacv and it stopped. I talked to many people that told me they had the same problem and the just replaced the eacv. so I replaced it and about 2 weeks later it has gone back to doing the same thing. just wondering if anybody in here knows what I can do. its in my 88 crx si with stock motor
