OK.. not that I can be much help here but I've had a similar situation but it followed me right down to idle unlike yours.
I pulled the IAC and it was BEYOND full of carbon. I cleaned it and tested the solenoid at the end of the valve with two test leads. The valve did not actuate. Now there is a 50/50 chance that you get the leads the wrong way as there is no way to determine (at least i did no research on it) which is the positive and which is negative on the plug end of the valve. So to double check my lucky guess and I switched my leads.. BAD IDEA.. as somehow I had it right the first time.
If your IAC has the little black cap on the top of it after you pull the valve of the intake take a flat head screw driver and pry the cap off and pull out the little filters in it. If you don't whatever you spray away in the valve will just get stuck in the filter. Some IAC valves.. even meant for the same year.. do not have that black cap.. as is the case of some part searching and ultimately the one i pulled from the local yard from the same year ranger as mine.
The TPS (Throttle Postioning Sensor) voltage test is explained very well and is easly done with a multimeter. Mine somehow fell within tolerance which surprised me with the way it was acting but it may very well be your problem.
The motto "K.I.S" or Keep It Simple should play out well in any trouble shooting situation. Grab yourself some cheap starter fluid and spray all potentials with the engine running.
My IAC replacemnt didn't fix my situation entirely but did impove quite a bit over what I had. Keeping with K.I.S and doing everything I have done so far I wil be pulling an intake from the yard and cleaning the crap out of it.
Of course.. what are the chances I happend to pull a bad IAC.. wouldn't that be some crap lol!
Good Luck!
MAF cleaner or UNchlorinated brake cleaner will work. I used one of those small pipe cleaners to get in there good.
