I have a 2006 Nissan armada Le I had a starter issue so I changed the starter and everything was fine as far as the car starting, but ever since I did that I keep getting some kind of misfire, took it to autozone and gave me a P0300 code. I decided to change the plugs, the intake gaskets but I still get this hesitation when I stop at a light and shaking. Still got the P0300 code. I checked the coils and see on cylinder 4 i have no spark coming in from the harness. There's no electric coming in from the harness to the plug. But that's only on the one harness . What can the problem be?? Please help me its been 3 weeks and no one seems to know the issue!

Vehicle: 2006 Nissan armada LE 8cyl

HI there,

If you don't have any power on the #4 coil, then check and make sure you didn't pinch a wire under the intake manifold. The coil has 3 wires, on it, a power, a ground and a signal wire. All of the coils get power from the same source, the ground location is the same for them as well. This leaves the signal wire. You would have to check the signal wire and make sure it's not pinched.
