Okay, my idle was working perfectly for about a week or so, then the issues came back with a vengeance. The issue is consistent when using the auto-start, so I decided to go after this first.
Just so everyone knows, I installed the auto-start when I first purchased the truck and has worked normal up until this year.
I check voltage drop through the Auto-start for all my ignition wires, and it was .2v, not great, but could be worse. The voltage would stay around 13.7 volts with all the accessories on. Now the real kicker is when the Auto-start times out, and the turbo timer kicks in the idle works normally. The timer is tied into the exact same wires but is only dropping .1v.
Here's a video I took just for giggles.......
Since this still appears to be a voltage issue, and the only time it has ever done this in the past is with low battery's........Does the PCM read system voltage in A/D counts?
