Question type: Maintenance & Repair

Truck missing really bad acts like its going to die. Had Cadillac converter
checked.  Shop said my #3 5 &7 injectors were bad so we replaced them.
Truck still running the same, computer still showing fuel to rich. They are now
checking the o2 censor. Any ideas? Had engine replaced and have had this
issue since.
