So I replaced the screen and O-rings on my FPR, the screen was coated with grime.
Started it up and ran great. I configured AE ScanTool and it reported no DTC's. Drove it for about 10 miles and the CEL came on, started to get sluggish.

Got home and plugged in the ScanTool and it reported this:
P1211 Injector Control Pressure Higher/Lower than Desired (Engine running.)

Then I ran KOEO Test and got:
P1280 Injector Control Pressure Sensor Circuit Low

Both having to do with Injection Control Pressure. Not sure where to go from here. It's strange that all of these problems started after I cleaned the thick layer of crud from the bottom of my fuel bowl to search for a leak in the valley.
