Hi John, > Does this still sound like a bad mode switch that will > leak only on certain settings? Any mode switch of our design that hasn't been taken apart, cleaned & re-lubed every few years is a likely vacuum leak. There is nothing hard about doing this job. When you look at it you will see how it comes apart to be re-lubed. The main thing that can go wrong is that if the diaphragm has been too dry & sticky then it grips which causes the tits to shear off on the other side. Once those tits are gone then you either need to replace the diaphragm or be creative with glue. Not much sticks well between plastic & rubber. But the DeLorean vendors sell nice replacement diaphragms. Cover the diaphragm with a thin light coat of silicone o-ring grease. The other thing to watch out for is to not loose the screws that hold the mode switch to the panel. One screw is longer and holds the face plate through the panel and into the mode switch. The other screw is shorter and only holds the mode switch to the panel. There are issues with the longer screw not being long enough, but if you buy a new diaphragm from PJ Grady then it comes with a longer screw. Walt ------------------------ Yahoo!
