Folks-

My van is idling a touch low, its usually 600-650 when warm. Its been like this for a long long time but I'm now getting around to looking at the specs, and see that for my '87 LE with Auto it should be 750.

I've got the FSM and it tells me all the stuff to do, its very straightforward. But I have one question: it says to remove the "ISC VSV" connector. Why do you need to do this? Why can't you just adjust the screw with a warm engine in neutral to 750?

Its just that I like to know the "why" sometimes, I have no problem disconnecting the connector if need be, not like its hard to do.

thanks!

Mark
