Is this an idle specific problem or does the engine also have some issues while driving?

Is this a hunting/fluctuating idle? Does the idle spend more time on the high side or the low side of idle speed?

 

I did the Fitv cleaning thanks to RonJ@ht it worked like a charm

 

It spends more time about high idle but once it starts its about half and half. I guess it doesnt miss when im driving...unless I drive for a very long time I somewhat feel of a performance issue maybe.

 

I cleaned my IACV but not as well as your write up explains. I will be doing both the IACV and the FITV tomorrow thanks for your write ups RonJ@HT. Do you have a shop down in Houston or something? I am from Houston but live in Maryland right now.
