My indestructable Xterra suddenly started running like crap after a about 80 miles of a 100 mile round trip. I nursed it home on less than 6 cylinders, hence it maintains its status as most reliable vehicle ever.
Anyway, P0304, swapped coils between 2 and 4, miss moved to 2 - so bad coil. I had a couple used junk yard ones I grabbed a while back so stuck one on - that seems to have fixed the miss. Changed the plug for good measure since I have a set here - there nearing time again - this plug has about 90K on it - spec is 105K change interval. Doesn't look good either, might have been missing intermittently for a while?
So anyway, should I change all 6 coils now that I have had one fail? I have the plugs, they are already in the to do category. I have a couple other items to do at the same time:
