Hi all
Ever since getting my D back from having a water pump installed it’s been idling at 1000rpm both cold and hot. Occasionally it will idle at spec when warm but most of the time even warm it is sitting at 1000. I’ve done all the usual checks. My throttle linkages are all set properly and the idle micro switch is being engaged. I’ve tested the thermistor and it’s fine. I will be doing a smoke text later this week but no evidence so far of a vac leak. If my decel springs were worn then shouldn’t I see idle at spec when cold (as the idle motor should be able to compensate) then it speed up when warm? I’ve read all past threads and mine seems different in that it sits at 1000 both hot and cold. I’ve also tested the idle motor circuit and it’s all fine. Thanks
