Anyone ever get this code..

= MAP sensor output / Injector / Fuel pressure / Intake air leaks / Heated oxygen sensor

I just got it last night on the way home. car started sputtering, reved the engine just before boost, and the a/f gauge just stayed burried in the red. Something happened, and there are alot of variables here. Any ideas?

still running the stock injectors, have a HP walbro FP, and a FMU.
is it possible for a disk to break/go bad in the FMU?

i also have a missing link... could this cause a issue?

Well thanks...
