I did check my ignition advance yesterday. At 50mph and a 21TPS (just enought throttle to keep it rolling and not loose speed) the advance was 35-36. Going slightly downhill at 50mph and a 19-20TPS the advance was 39-40, which I presume is max. Idle TPS is 17. I need to test this with the line pluged back in to compare. This is quite a mystery, I did a little drive last night, I often drive this route and have never gotten better than 40mpg, last night I got 42. It definatly is working...and I'm not getting any pinging or surging that is typically associated with vacuum leaks.
