If you are using a manual ECU with an auto tranny and no VSS you will get those stalling issues like you described. I had this issue when I switched over to an auto tranny. I switched to the auto EECIV and it worked good with no VSS. It still idles down pretty far when coming to a stop but doesn't stall. This is on a 5.0 though. How did you get the pip signal from the caddy ignition?
Back to the VSS thinger. No mine isn't plugged in nor is the speedo plugged in. I think that VSS has 4 or 5 wires and is a round shape plug. The funny thing is not only coming at a stop does it do a low idle but also going down the highway it boggs some times like its not getting much fuel. Would the VSS wire do that also?
