I have an 89 Gt and it is idleling at 1,000 rpms or just a little over. When it sits and idles it will drop to about 800 rpms but that is after a couple of minutes. Is there any way to adjust this? Also i was wondering if anyone can tell me why when i am driving and i push in the clutch the rpms do not drop all the way to idle until the car comes to a complete stop. They will drop gradually until about 1500 rpms, then when i come to a complete stop they will go to idle speed. I really noticed this after i put the 65mm TB on but i don't know if that has anything to do with the problem. Thanks alot guys
