Joel , I should have mentioned that my system is '91 Jetta-Golf Digifant II which is similar to Vanagon Digifant. My engine is from a Golf (formerly Diese 1982 Westfalia). In the 8 years that this has run the engine trouble-free, the last 7 months have had gremlins on board. I did clean the throttle body and adjust the idle and full throttle switch, and that restored my power, fuel economy and warm up, which had been erratic. Now the power is back, the idle still isn't as smooth as it used to be(all the tune -up stuff has been done). What specifically is reset when the key is turned off and then back on is the question. When the stalling begins, unless the key reset action is made, the engine goes into a wildly fluctuating idle up over 2,000 rpm and then down to 500 rpm and back up rapidly repating this cycle. The exhaust smells sulphur which means rich mixture. There are no air leaks. Does turning the key off and then back on reset the ecu for a variety of components, or only one. Of course I'm trying to find which senesor is flipping out the ECU. Or if the ECU is defective as has been suggested. Robert
