87 Mustang GT carbed...noticed my exhaust started smelling rich and I checked the fuel pressure (holley fpr has a gauge threaded in) and it was at 10psi 
Last I set it was at 6psi and when I went to lower it, it wasnt loose like it had backed the screw out or anything
When it was up at 10psi, I dont mean it spiked to 10, I mean it stayed at 10 until I lowered it to 6psi (again)...what would cause this, maybe a bad fpr? If so I installed it new in December talk about a short life
