[BFix] EFI Help

[Ken]

Hello all,
 
 
I'm helping a buddy do an EFI swap. He is using a 1988 Mustang 5.0L HO (non-MAS air). He got the motor from a crashed Stang and it ran like a top with the car. We've got it swapped over and the wiring hooked up and the engine starts but runs really bad. It stumbles really bad and pours black smoke out the left bank and will not idle very good, almost like it is running to rich. It has been timed to 10* w/the spout unplugged, he put a new dist. and mod. in it, and TAB & TPS. He did not put the EGR back on or the purge container. WE have found no vacuum leak such as open ports or hoses on the intake. We are 99% sure the wiring is correct and will be checking that tomorrow.  What more should I be looking for?
 
TIA for any info,
Ken
