I've noticed that the Batmobile (that's what I call my Bullitt:smile: ) wants to idle up around 1000 rpms alot. If I hit the accelerator it will come back down to about 750 where it's supposed to be. I made the IAC restrictor hoping it would fix the problem but it didn't. It does fix the hanging rpms though and that is nice. This benefit is especially noticable at start up. Any thoughts?
