Hello again!!! I now have new problems!!! The throttle cable is fine!!! I am finding it very hard to find vacum leaks!!! And I dont know where the idle speed control valve is!!! However now my temp. guage perminantly sits at cold and the pipe coming out of the thermostat is swolen!!! After changing the thermostat and bleeding the system the problem is still there!!! Any suggestions???
