I am getting a intermittent misfire and am noticing the car stubble and drop rpm a little at idle. A couple weeks back i was doing some wheeling and cylinder 5 misfire check engine code popped up. I cleared it several times during the wheeling trip and hasn't come back on normal mall crawler duty.
I inspected all the coils on the same side and swapped coils to different cylinders to see if the misfire would move to another cylinder. The car has 225k miles on it and a couple of the coils have fine hairline cracks in them but the boots are soft and pliable. Plugs were changed 35k miles ago.
Last night checked on techstream and cylinder 5 is still having misfire events.
So i am thinking I should pull the spark plug and inspect since the misfire didn't move with the coil swap. Any other suggestions?
