I rewired the power wire for my system and when I started back up my car it had a hard idle of constant little revs. I am assuming this is normal and when I wake up tomorrow it wont happen again right? When I wired my system the first time it didn't do this.

 

maybe you need to do a throttle body adaption?? I dont know.. just taking a stab in the dark

 

Yea if you dissconnected the battery it would be wise to do a TBA, you can do it through a VAG or without it. Even after you do a TBA the rpms will bounce at idle for a little while. So yea tommorrow it will be likely that the RPMs will bounce but it should go away.
