Sounds like the isv isn't functioning correctly at all. On a motronic car there is no "bypass", so the isv is the only thing that makes the car idle. Did it idle high before you swapped the connectors? If so it could be your throttle microswitches, and you did have the connectors right. I would try swapping the connectors back and checking the switches with a multimeter. _____________ 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
