1985 Honda CRX Si, fast idle switch no longer available - I need one of those. Any suggestions of how I can get one?
“No longer available” from whom?
Have you tried your friendly local junk yard (excuse me, auto recycling facility)?
Ask on the following websites:
Those are about your best bet to find people who still know a lot about where to find stuff for the CRX. A good resource, especially if you have a 1st gen - those are getting rare.
I’m not sure what a fast idle switch is but if its the idle air control, Rockauto.com has them.
