FOULED PLUG

2002 Ford Taurus • 150,000 miles

I got a bad miss and loss of power, 5 plugs are burning nice and white and 1 is black as tar. I changed all the plugs and the crank sensor, it seemed like it made a difference ideling but when the wife drove it she said it didn't fix it. I was wondering if it was internal like bad rings or maybe something a little easier like a plug wire.

I would start with a compression test to see what the cylinder is doing.
