Recently I acquired a grimmspeed ebc, installed it and got bad idle, wanted to dd the car til the dyno time in 3 weeks. I knew this would happen but not this bad of a idle. Hooked up the OE controller, does it matter how you hook up the vacuum lines? When I took it off I never paid attention where the vacuum lines go until the ebc install.

 

Look on the hood of engine. It shows you the vacuum points and everything. That's what i used.

 

Different hood installed. Tried that

FYI your idle shouldnt be affected by installing the solenoid. If you are just putting around the solenoid isnt really doing anything. I would recheck how you have your vacuum lines hooked up as well as make sure you dont have any vacuum/ boost leaks.
