Vacuum leak. Check out your intake boots, tubes routing to and from the ISV, and injector seals. Also make sure that the idle adjustment screw on the throttle body is tightened completely and the accompanying o-ring is sealing well. Check the wires and connector to the ISV. I have mine disconnected and it runs as you describe.
Jim Weinheimer [email protected] 85 2.0L 16v GTI 85 Golf >Ok here's the deal, when the car is cold upon first start up, it has trouble keeping an idle, and sometimes will even die. Once the car is warmed up, the car will idle, but way outta tune, it's almost like the engine is burping, the idle will bounce between 1000rpm and 1200rpm, really strange. I was thinking it's the idle stabilizer going out, but someone else told me it could be the o2 sensor, or possibly something with my motronic. If you've had this problem before, and know how to fix it, drop me a line, much appreciated.<BR>Thanks,<BR>Pat</DIV> ><DIV>92 GTi 16V</DIV><br clear=all><hr>Get your FREE download of MSN Explorer at <a href="http://explorer.msn.com";>http://explorer.msn.com</a><br></p></html> >_____________ >List Sponsor: http://www.netsville.com >To remove yourself from this list, send mail to [email protected] with 'unsubscribe a2_16v' in the body of your message >See us on the web at http://www.a2-16v.com >Visit the 16V Homepage at http://www.gti16v.org > > _____________ List Sponsor: http://www.netsville.com To remove yourself from this list, send mail to [email protected] with 'unsubscribe a2_16v' in the body of your message See us on the web at http://www.a2-16v.com Visit the 16V Homepage at http://www.gti16v.org
