Here's this problem. Doesn't happen too often.

About a year ago I put new plugs in the car, but the only plugs I could get were Motorcraft plugs. I was stuck since I had the number 3 plug blow out of the head which damaged the plug.

Now when I'm accel from a light or stop sign, with the same pressure on the gas pedal the car will buck a little bit and then take off. I will watch the tach go up and down very slighty then the car will rev off from say 2300 RPMs to 3500 RPM and shift gears and drive normally.

Is this the plugs?
