I've had a persistent high idle, and very high starting rev, on my 89 XJ. Decided to look at it today. Cleaned the stepper pintle and it's seat. Looked fine. No change.
Disconnected various vac lines, and noticed that each disco would up the idle (as it should), but when reconnected, it would stay down, until driven or restarted.
So, it seems the stepper is doing _something_... So, while it was down at about 800 rpm in N, I disconnected the stepper. Now it stays at a proper idle at start and all conditions (not tested cold starting yet).
Does anyone have a diagram or specs for the stepper so I can test it without the exerciser? It's just a regular stepper, but what's the pinout or voltage rating?
Any ideas on what might be going on otherwise?
Thanks,
