[Peugeot-L] Re: 89 405 Mi16 high idle problem

Just recently we have replaced defective throttle position switches on two different MI16's. The symptoms started as an intermittent problem but got worse over time. When the switch worked correctly there was of course no problem but when it failed (does not signal that the throttle is closed) then the idle would be always consistently 2000rpm. If you think it is the switch you can always unplug it during a time when you are idling high and then jump the terminals at the connector (2 and 3 I think, the bottom two, I can verify later if you don't have a manual) and if the idle drops back to normal then you found it.

If your idle rpm is high but varies then I don't think this will be your problem.
