Thanks for your reply. As mentioned in my original post, I did the exercise of swapping coil between 4 and 6 cylinder. I am still getting same error code p0306.
I changed sparkplug in cylinder 6(the original spark plug had some burn mark in porcelain surface) and tried again. Still same p0306 code.
That is when I thought may be we have separate air intake for each cylinder. If common air intake is leaking, then misfire should happen randomly in all cylinders.
The other possibility is proper signal not coming to ignition harness. Don’t know how to check that?
Again, thanks for your reply. If you have any more ideas, let me know.
