I have a 1999 3.0L 2WD Ranger with 115k miles.
I bought the truck about a month ago, and two weeks ago it started doing this. It only does this after the truck has been driven awhile and then shut off, and it only does it at idle. When it happens, the best way I can describe it is that the engine chokes up and wants to die (it hasn't actually died yet). While it is doing this if I give it gas it takes it about a second or two to actually rev up, and when it does a lot of black exhaust comes out. Once the engine clears itself out it, it usually runs fine for a little and then repeats. Sometimes this keeps happening (every time it goes to idle), sometimes it happens once and then it is fine. The engine runs fine while I am driving around. I don't notice any loss of power, etc (idles a bit rough, might have a slight miss at idle).
So far I have replaced all of the plugs and wires and today I replaced the EGR valve. The only thing I can think to do next would be the O2 sensors, but I thought I would ask here before I go waste more money. I don't get any CEL's (they might be burnt out), and I have not read the codes yet.
Any and all thoughts or comments are appreciated. Thank you!

I also removed the MAF sensor and let it soak in cleaner for 12+ hours.
