During some recent problems with my EFI I happened to find something interesting. I was studying the manual and the exploded diagram of the fuel pressure regulator. I found a screen on the inlet side. So i removed the regulator and pulled the side off and found the screen plugged shut and 1/2 of the fitting full of junk. Mostly rubber pieces from the old hoses i replaced earlier. This screen is on the inlet side of the regulator after the fuel rail and will cause overpressure to the injectors. My engine was acting strange and idle was terrible. Loading up and all sorts of things. Now she runs like a new machine. This may have come up before. If so im sorry. Sorry for no pics. Hopefully this helps someone.
