    I have a 2018 3.5 V-6 with a continuous misfire at idle, when the engine accelerates it will stumble and buck until it reaches 3500 rpm and then it clears up and runs normally.
    As you know this engine has both port and direct injection and I'm just wondering if anyone has had experience with this fault and which circuit is "B"?

    Didju do a visual inspection already? Looking for mice n stuff? I think your instinct is correct. That it's the port injector and after u get going the direct injector is taking over. Although I have no proof of that.
