1999 Mercury Cougar V6 uncontrolled acceleration

Description

Here is the strange problem that has plagued my car for a while now. I have replaced the IACV and TPS and it didn't fix it. EDIT: I believe I found the problem. One of the bolts holding the EGR to the UIM was broken off, and was allowing a vacuum leak around the EGR where it wasn't sealed down tight. I've got a new UIM coming, and will update if that fixes my problem!
