Help with sporadic high idle
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.
