I'll check the vaccum connection next time the instrument cluster comes out. Right now everything works except the economy guage. So I'll leave it alone.

The first time I had the instrument cluster removed (just to change 1 light bulb), lots of things went wrong....both cluster lights burnt out, RPM guage stop working, and the clock stop working. I did more damage than good removing the cluster. Unless this vaccum leak is affecting the performance of my car, I can live without the economy guage.

Thanks for the advice though.
