What exactly are you trying to find out about the low idle? It is adjustable on the throttle body.

I figured out what was going on. supposedly on ford rangers the Idle Air Control Valve (IAC Valve) goes bad. i got a trouble code looked it up and sure enough it is the IAC Valve. Under 100 bucks for the part

The only adjustment you'll probably need is to get the air out of the clutch line. Loosen the bleeder screw, and put a two or three foot vacuum line on it. Submerse the other end of the line in a bottle of brake fluid. Pump the clutch untill no more bubbles are coming out of the hose into the bottle. Be sure to keep the reservoir topped up while you do this. Hold the clutch down, and tighten the bleeder screw. Some hydraulic clutches do have an adjustment on the rod that goes from the slave cyllinder to the pressure plate. I'm not sure about yours. If there is a nut on the rod, you can adjust it somewhat. You want it set so that there is just a little bit of play between the rod and the pressure plate where the rod goes. If none of this helps, you mayneed to replace the slave cyllinder.
