skipping and idling high

skipping and idling high
my truck is a 98 2.5l 2wd Ford Ranger
It has a k&N cold air intake flowmaster exhaust.
I just put a new I.A.C sensor,Throttle positining sensor i cleaned the M.A.F sensor,and replaced the throttle positioning sensor.... I don't know what else to do or check.
Your help will be great.
it idles fine but if i start to role with no gas being applied it starts to gain rpms, it will reach about four grand then idle down when you sto rolling.
while idling if you roll on the gas it will bogg down, but if you can get it above 2 its fine
when you come to a re light or stop sign i will gain rpms up to 4 or 5 grand for about 3 seconds then idles down
I can usually figure out whats wrong with my truck but me and some of the mechanics i've taken it to are stumped

This weekend i changed all the plug wires and four of the plugs... the other side checked out fine. Cleaned the EGR, cleaned the throtle body,and the MAF... it doesn't sputer while going down the road anymore, but can't it can't deside if it want's to idle up or idle normal.
Went to Advanced and let them put if on there hand held computer and it gave me a read out that goes a lil something like this
<Idle air control overspeed error
<Catalyst efficiency below threshold (Bank1)
<System to lean (Bank1)
I was told and even looked it up and " Bank1" stands for(The bank of cylinders containing cylinde #1
Don't know what that means figured i would add that to help you help me
Thanks
