2005 x350 with misfire cyl 1, 2, 3
 

Hello forum,
I have 05 xg350 with misfire in cyl 1,3,and 5. everything has been replaced as in wires spark plus, wires. also the bank 2 sensor 1 reads real high in readings. What could the cause be?


the oxygen sensor has also been replaced and didnt change anything.

The high readings on the O2 is just because those cylinders aren't firing and not burning the fuel. I'd look into the injectors on that side. They may be leaking fuel. Were the plugs you replaced fuel fouled?
