1996 ranger idle real high
4.0 i believe. helping out a friend it Idles high started out at 3000rpm. replaced the TPS and the IPS (idle pos Sens) now it idles at 1500rpm. No codes to go by. does anyone have a link for the the service manual? or know what and how i should check the next....... Its my understanding that there isn't a way to manually adj the idle speed.
