wierd problem

[94redranger]

Today driving home from work I was going along good then suddenly my truck just started bogging out so i floored it and it went good again. When i was stopped the idle dropped from my regular 1500+ to below 1000. Then it started running really rough until it slowly died. I started it up having to give generous gas and it fired and I had to keep reving it to stop it from dying. Weird thing though this happens intermittently. It will be going good then just bog out. I know one of the o2 sensors is bad because a while back I got some rich/lean codes and once warmed up the motor misfires due to faulty o2 sensor. So I am thinking O2 senors and IAC. Does anyone else have this problem or would suggest other things to look for? thanks
ps anyone know a good way to get rusted/seized o2 sensors out?

Clogged fuel filter?

Probly not clogged fuel filter because it runs good when it is running good plus I changed it recently.

ya 1500 rpm is a really high idle i dont have a 4l i got a 3L an it idles at like 800rpm an like 1000 when its cold out then drops to 800 or so when it warms up.
