2001 Ford Windstar 6 cyl Front Wheel Drive Automatic 140k miles

I was working on my sable, and came acros a product called sea foam. So I used it on my sable. I liked the results so much I used it on my windstar, and have been having problems ever sense. I have changed the idle air control valve, because it deterated the diafram in the valve. Cleaned the egr valve, and changed the spark plugs, they were the sugestion of the parts house. After 140k they tend to open the gap, and it did 3/16''. So now most of my problems are solved, but it still cuts out when you are barly pushing on the gas pedle, not all the time just every once in a while. I just put a plug in the vacuum line on the egr to see if that's the culprit.
Will the egr leak and cause this problem, or would it be all the time.
Do you

But it still cuts out when you are barly pushing on the gas pedle. Check and test all of it

Dirty fuel injectors (cleaning the injectors often fixes this).
Bad MAP (manifold absolute pressure) sensor
Bad TPS (throttle position) sensor
Bad or dirty MAF (mass airflow) sensor
Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
Bad gasoline (fuel contaminated with water or too much alcohol)

Sometimes, what feels like a hesitation is actually ignition misfire rather than lean misfire. The causes of ignition misfire may include:

Dirty or worn spark plugs
Bad plug wires
Weak ignition coil
Wet plug wires

So Last night I cleaned the MAF, and after cleaning that I noticed oil residue on the throttle body. So I completely removed the upper front cowl and took the intake manifold apart, to find it completely clean on one side and gunked up on the other. Found the EGR ports clogged on the fan belt side. So after three bottles of cleaner a shop vacuum some relay small brushes I cleaned it. Oh yea I replaced the PCV valve. AND IT RUNS, So here is the thousand dollar question, Whats next, And why dose this happen, Do we need to drive the car more aggressively so it will clean its self, Or should I just plan on cleaning it on a regular interval.
