My understanding is that > a reaction should happen right? You can suck on such a hose to verify that there are no large air leaks into the PS. If there are, you can carefully disassemble it and seal the leaks unless the leaks are due to a diaphram that is corroded away. This never happens in the type 3, but does in the 914 where the PS is mounted just under the battery. > plus being the occasonaly dumb person i am, i adjusted the screw on the > back of the sensor. yes i know, but hey, lots of power. downside is no > matter how miniscule i tweak the screw, i havent gotten better than 15 > mpg on town 20 highway. down a ton from the previous 20+ in town, 28 + > highway before i had the power loss. I would almost be willing to bet that your voltage regulator is at the end of its life and your system voltage has fallen to ~13 volts. Measure it. If it is less than 13.5 V at medium RPM then just replace the voltage regulator with a BOSCH and you may find that wonderful and unexpected things happen.
