fuel injectors failed on 2 cylinders fuel injectors failed on 2 cylinders

Truck had 154 misfires on cyl 4 and 2 misfires of cyl 2. Or dealer tried to change only one set of port and direct injectors. They tried to return the truck. I refused to take it because I knew the inspector was coming. They assured me the truck was fine but then when the insurance came, there was still a misfire so they had to fix the other cylinder as well. Try to double dip on the diagnostics. However, they never fix the problem the first time. Not all cylinders misfired only cylinder to two and cylinder four.
