This one is driving me nuts! I've been working on getting my VE table in line and making good progress but my idle will sometimes be ridiculously high when I come to a stop. I've just noticed today that when this happens the sensor data in TP shows idle mode to be off idle. My TPS data show 0.53 volts & tps% 1 or sometimes 0.51 & 0 with VSS @0, but IAC counts sometime as high as 100. When it does work properly, I've seen it go to idle mode as soon as VSS is below 4 and the IAC counts drop to 10-15. I have short logs of when it does both if anyone can help, this is a 7747 with $42 mask.

Thanks,Chris.
