Hey there! Try this. While I did not have an "idling problem", I did have problems with my truck as well. I found (2) problems: the first one was, my crank sensor wires were shorting out (causing an intermittent motor cutting out/restarting thing). After I fixed this, it would still cut out at times. I found a video on YouTube: (

This video is about repairing the PCM and while this is about a full size truck, the PCM is very similar to what is inside ours. It showed (3) capacitors that had worn out and how to replace them. When I pulled my PCM, the capacitors were shot, just like in the video. I did replace them and the truck has been running fine since. It is not my DD, but fires up and runs just fine. It is possible, since you have replaced the major sensors, that the PCM could be messed up. I hope this helps you out.
