Stepper plunger worn oddly

Hi all - haven't posted in a while as the 90 doesn't get a lot of use these days. I just got back from overseas and she didn't want to idle, so I pulled the stepper to clean and noticed it is oddly worn on one edge. Concerned the worn part could be matched on the seat. It seems to have fixed for the most part but the idle falls after a rev and almost stalls still.

Any input would be appreciated.

ps - so many awesome Defenders in France. The TRDs were lined up on the Champs Elysees.

maybe the stepper is not seating in streight so it is wearing odd. And if it is worn enough it could be causing the idle problems, also not being run for a long time could cause idling problems so you may want to take it on the highway for a little drive to let the ECU fix it self.

Is the ECU really that emotional?

It was still failing to idle, so I pulled the stepper out, turned it upside down, refit, and all fixed, runs great.

Anyone with idle problems, try it out.
