Today I managed to find a little time for my project after replacing the map sensor and some other tune up stuff on the Passat.
Most importantly, I found the guts to drive it down to the gas station and fill it up. It's the first time that there has been enough fuel in it to make the gauge actually registered anything. Nice to see it working!!
And of course, I tinkered with the throttle linkage and the idle a bit more so I could take it for a burn around the block. Sweet!
