could this be why I have a misfire on both 1 & 2?

Crank sensors are usually all or nothing engine runs or not.

ok guys i finished my jeep yesterday and i really dont know what it was.....bc i did multiple things.....i replaced the oring on the cylinder 1 injector....switched it to cylinder 2 then put a new o ring on the #2 injector where it plugs into the block......then i taped the whole wiring harness that runs next to the fuel injectors along with the wires into the injectors......conclusion been running since yesterday no issues...no fuel leaks no misfires..nothing......runs like a champ....and i replaced the spark plugs the first night...so im holding onto the coil pack i bought and waiting about a week to see if anything pops up...
thank you guys for all ur input it really helped and i was able to get the issue resolved with minimal cost/work
thanks
Josh

Whatever happened here. I have the exact same issues. Replaced everything, crank position sensor, pulled the injectors and had them checked...they are saying check compression, I am guessing fine....

I am not going to replace the brain....what happened here?
