Periodic chug in the engine
I have a 2005 Exploer Sport Trac with 236K on it
recently changed all plugs & wires as well as the coil pack to stop a sputter in the motor. it worked. now, very periodically and only for a split second i will loose all rpm and then back up again to normal. I was told that the computer may be going but i've plugged it in and it wont turn on a reader. other than that one hickup she runs like a dream now. can anyone help.

Forget high tech wizardry, check your engine and chassis grounds. A bad connection can cause all sorts of electrical mischief.
Don't listen to people that tell you the computer is burned out, PCM failure is actually pretty rare.
