A few weeks ago my 1992 Loyale Automatic started idling funny. It would fluctuate constantly. My mechanic told me that I needed to replace the Idle speed control solenoid.

So, my question is: Does there need to be any timing done before it will function correctly? I've put the part in, but now the RPMs jump up, and then drop to zero after a few seconds.

Did you replace the whole unit or just the solenoid on top?


If just the solenoid on top the it has to be ajusted so that the engine runs at around 750 -- 800rpm at idle.


If you replaced the whole unit ( with a new one) it should idle at around 750 -- 800rpm once in place.
