tps evaluating for ii issues

[max]

Low idle/stall condition is back. Rode the bike to a restaurant tonite about 5 miles (mostly freeway) from home and it ran perfectly (stopped at 4 stop lights). I stayed off the freeway on the way home and stopped to get gas, when I discovered the slow idle condition was creeping back. I rode around my neighborhood only 3 more miles before the 700 RPM idle condition was back in full force. I immediately pulled into my garage and turned the bike off with the key so that I could remove the seat and connect my meter to the negative battery terminal. I performed the voltage tests at the TPS with the TPS connected, and the results were slightly different from the last time I performed them.
Bike off:
Black/Yellow = 4.6 volts (last time I measured was 4.8 volts)
Black/Red = 0.45 volts throttle closed, 4.6 volts full throttle
Black/Green = 0.0 volts

Bike running:
Black/Yellow = 4.6 - 4.8 volts (yes, it went up)
Black/Red = 0.5 volts bike idling, voltage increased with throttle opening
Black/Green = 0.0 volts

I started the bike and kept it in the garage, TPS connected, blipping the throttle, all while measuring the voltage at the Black/Red connection. The idle remained constant, at about 1,050 RPM initially, but the voltage at idle varied from .4 to .5 volts. After about a dozen blips of the throttle the 700 RPM idle returned, and after about another half dozen blips of the throttle the engine stalled. Each time the RPM dropped to 700 RPM it would slowly work its way back up to roughly 1,000 RPM. At no time during the 700 RPM idle and gradual increase to 1,000 RPM condition did I observe any difference in the measured voltage at the Black/Red connector, even when the engine stalled. After the engine stalled I immediately checked the voltage at the Black/Yellow connection. Initially I was getting zero volts, but after playing with the sewing needle connection I again measured 4.6 volts. I don’t know if my initial measurement of zero volts was the result of a bad connection with the sewing needle or not. I repeated all of the voltage tests described above and the results were identical. I did NOT turn the key to the off position, and restarted the engine. The low idle condition was still present, and the Black/Red voltage remained the same. I turned the bike off with the key, let it sit for about 30 seconds, and restarted it. It was idling at a normal 1,050 RPM, and there was no change in voltage at the Black/Red connection. I turned the bike off and came in the house to report these results.

Good work Dave ,did you get any of that on video and if not can you try to do that?
