Idle Speed Control


Recommended Posts

Can anybody relate? The idle speed control unit on my 92 seville keeps wanting to increase the rpms without cause. It will do this while idling and while driving. 2 Caddy dealers are completely stumped. I have replaced the ISC unit twice with no results. Can anybody relate or offer suggestions as to what may be causing the problem? The only code on the computer is the code for a faulty ISC unit. Hence, replacing it twice. HELP!!!!

ISC was addressed many times, and the related information in the archives maybe all you need to know. Check it out first, and if it does not help or you have more questions we'll try to help.
