Code 43 fuel delivery issue

Started with car stalling out on freeway and would not restart. Towed the car home. Replaced igniter in distributor which solved the no start issue. Short Test drive that night seems ok. Son drives to school and back and complains car has no power. Step on gas get high rpms but no power. Get a CEL. Code 43 fuel delivery problem. Have set timing, replaced o2 sensor, checked vacuum leaks, seems to be getting fuel. Injectors are firing.

Car will idle all day and never dies out but when try and drive it just doesn’t want to go.
