X15 1659 Code

Hi Rawze,

Thank you for the quick response, so it is possible that an exhaust leak can make an injector driver code active? Or a misfire? Wouldn’t it be more than just one injector? It’s been bugging me, I’m def going to start with an injector leak down test and go from there first. Just been struggling with this thing for a while. Seems like these injectors are a little More sensitive than the injectors in the ISX15s. If there’s an exhaust leak & it can trigger a misfire is new to me. But this is my first time really digging deep with these efficiency series Cummins motors.
