I came home in my 98 Ranger and noticed it was not running as smoothly as usual. I wouldn't quite call it rough. I parked and went inside. Next day I started it and when I went to put it in drive, everything seemed normal until I pressed the throttle pedal. It would not rev up at all. Neither will it rev past idle speed in neutral. I can press the pedal to the floor or anywhere in its range (except idle) and it will run very rough; it sounds like it's "hunting" but will not stall. As soon as I let it go back to idle position it idles smoothly. It has thrown no codes; I have a scan tool. Neither has the check engine light been on. I am not completely familiar with the parameters in the live data portion of my scan tool, but I noticed that the MAF numbers don't change much when pressing the throttle. It seems to stay around 5.xx grams/second whether idling or opening the throttle. But a search online for MAF symptoms doesn't describe not revving up at all, and seems to say that the ECU can keep it running by using other sensors (limp home mode). So I am asking for ideas. The truck has about 160K miles on it and has always been super reliable. Thanks.
