I have 2004 nissan quest(64k) with same code p0306. I took cue from above post to find position of cylinder 6 and replaced coil 6 and 4. Still problem comes in 6.

Then I replaced the spark plug in cylinder 6 with new one. Still same code p0306 comes. Ofcourse, I do disonnect battery and erase code before both the tries.

Below are my questions:

1) Is air intake separate for each cylinder? If so where I can locate it?
2) If air intake is common for all cylinders, then can a single cylinder miss fire if we have leak in it?
3) How to check the harness of ignition coil(whether power comes to it or not)?

Appreciate your answers folks.
