4.0 KEEPS DESTROYING 2 PLUGS MOTOR OVERHEATS

1994 Ford Ranger • 94,000 miles

Blows spark plugs (2) 1 then the other and overheats after driving short distance. Replacing the spark plugs and the vehicle runs great.

What does "blow spark plugs" mean? What is happening to them?

Porcelain blows out and it overheats. Middle plug on drivers side. Rear right plug (passenger side)

You're saying the porcelain breaks right off the plug?
