90q20v Starting/Idle problem

[Thomas Edwards]

Guess I should have checked the archives and tips first :)  I have to take
it on a long drive today so I got a little anxious...

The problem is almost totally gone today.  ISV sounds like a likely culprit,
I'll check it out, clean it up and see how it goes.  Thanks for the
responses,


Tom Edwards

First thing I'd check is the ISV:
