Misfire #3 cylinder V70-XC70 2000

2000 V70 SE, 252K miles, AW-5, Denso,

Have read this both ways:
- A fouled spark plug can weaken the ignition coil (on plug)
- A weak ignition coil can foul the spark plug

Is one generally more correct than the other?

Anyway, #3 cylinder is beginning to show a trend. Engine misfire lights up the CEL. It's always been #3. I'll test the coil by swapping with another. Coil tests good. I'll then replace the #3 plug and misfire goes away. Good for 500 miles or so, then another CEL with #3 misfire.

Guess the next step is to replace both the coil and spark plug with new parts and see how it goes.
