SOURCE: 1997 ford ranger idol problems
I have a 1997 ranger xlt 4.0l 4 wheel drive. I had a similar problem. The pipe going from the egr valve to the intake plenum had a hole rusted in it right behind the egr valve on the bottom of the pipe. It took me months of looking before I found this hole. I removed the pipe, repaired the hole, and the engine has been fine ever since.

Fuel system..Filter or pump..maybe clogged
Try fuel line cleaner..make sure the tank is 3/4 full.
this may help.

Here are the most common causes of idle surge, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake
