The main problem was a ruptured fuel pressure regulator (FPR).
IF THE IMAGE IS TOO SMALL, click it.
To get at it, I had to remove the throttle air hoses (so I pulled the filter box to wash it out), most of the secondary air control valves, and the coil bracket. The
MotorCraft CM4764 FPR is ~$85, so I opted for this ~$25
Standard PR15 because it's a brand I trust.
I also pulled the fan & shroud to clean & inspect more of the engine. I still have to repair an exhaust leak on the Right side (due to someone installing gaskets), and I want to change the engine mounts, so I might pull the Left side manifold, too.
