I was trying to adjust my fp the other day(kirban afpr). My gauge shows 30psi at idle with vacuum connected or disconnected. So i unplugged the vacuum and turned the screw. The gauge didn't move. I turned it probably 6-7 turns and the gauge still didn't move. I figured the afpr was broken. I also just got a 77 pro-m in the mail. I tried to put that on after doing the fuel pressure and the car will not even make it around the block without dying... and the check engine light goes off. So i put the C&L back on, it will run fine but is way way down on power won't even spin the tires in first. My fuel pressure gauge is still showing 30psi, I am thinking maybe the fuel pressure gauge is broken? It goes to 0 when i turn the car off. Or is the kirban probably broken? Also i didn't reset the computer between changing the mafs, could that be the problem? Help!
