Parking17 Posted January 8, 2010 Share Posted January 8, 2010 Hello, Have a 2004 IS with 80k on it. Runs great. Problem is when I sit in traffic or a drive thru, engine almost dies when the cooling fan comes on. When the fan kicks off, idles normal and smooth. No lights on in the dash. Is there a relay or switch that should be advancing the idle when the fan comes on? Quote Link to comment Share on other sites More sharing options...

Parking17 Posted January 12, 2010 Author Share Posted January 12, 2010 Engine has now stalled twice. No Check engine light or code. Starts right back up. Quote Link to comment Share on other sites More sharing options...
