I was wondering if any other rx7 owners have experienced this problem. MY 87 rx7 turbo 2 bac doesent seem to drop rpm when i pull the connection from the bottom. I thought this could be a short or a prealude to a bad bac any advice would be much appreciated thanx

 

This article http://www.teamfc3s.org/info/articles/idle.html and look down toward the bottom of the article. Applies to turbo and non=turbo. I had a ECU problem and fixed it according to this article. He gives part numbers that can be had a RadiosShack for a buck or two. Easy solder job after removing the transistor.
