Why does my Ford 2002 f250 gasoline engine idle rough and loses power?

Something in the air intake system may be dirty. Remove the air intake plenum inspec to make sure it isn't plugged. While you have this off and with the engine running, clean the throttle body with carburetor & choke cleaner. Have someone keep their foot on the gas so it won't stall while you do this. Also clean the MAF (Mass Air Flow) sensor with MAF cleaner. The MAF is used in conjunction with the oxygen sensor(s) to control the engine's air/fuel ratio accurately. The MAF is in the air intake plenum.
Did this to my son's F250 Superduty and it runs like new.

Mitsubishi Galant engine stoplight comes on and car loses power when I go over 100kph Then it runs rough Drives fine at lower speeds Just had cambelt changed and engine steam-clean What is wrong?
I highly suspect the plug wires are bad or moisture has gotten in them. At higher speeds and throttle openings, the spark has a harder time jumping the spark plug gaps. If the wires (or path) from the coil to the spark plug gets restricted or shorted by water, the spark cannot reach the spark plug and the engine looses power and runs rough.
