I just rebuilt a 1986 5.0 HO mustang. I put a new Ford racing E303 cam in it ang got the heads reworked. New hyperteutic pistons and all the normal wear items. I also got 19LB Bosch injectors. Removed all egr and emission controls. The problem is that when the engine gets warm it will not idle, it kinda surges and then it burns so rich it will run you out of the shop. I know about speed density vs. maf and this year has the sd with eec-iv. Is there anyway to correct the problem I'm having? I've replaced all sensors: MAP coolant temp, air charge, etc.
