1991 Ford Explorer, Eddie Bauer Edition, V-6

Vehicle stalls on deceleration. Computer codes are 14 and 66.
Auto mechanics tested computer and said it was transmission solenoid. Transmission mechanics said nothing wrong with solenoid. Original mechanics tested again and found nothing. Told me to take vehicle to ford dealership and pay them to test. Prior to stalling problem, had oil leak in oil sending unit. Replaced oil sender then when test drove it began to stall when coming to stop or slowing to turn. Friend recommended changing crank sensor, this made no difference.
