Can a DRB-III read target idle speed?

I'm having a really screwy idle problem with my Neon, and it seems like it's in the PCM. Any of you with a DRB-III, or at least access to one, can you tell me if target idle RPM is a parameter that can be read?

Randomly, I'll be driving along and I'll get an unsettling "automatic-y" feeling where I let off the gas, but the car is still applying a small bit of power to the wheels. Pressing the clutch in, I'll get somewhere between a 2k-3krpm idle. When I come to a stop, the engine will slowly idle down, eventually getting to a normal idle. Once I take off again, the same thing happens. Here's why I think it's in the PCM: if I turn the ignition off for a second or so while the car is in gear and in motion (momentum keeping the engine turning), then turn it back on, the problem is gone. This is also the case if I shut the engine off and restart the car.

I've already removed and cleaned the IAC, as well as checking the wiring to it.

We've got a DRBIII at work. I can hook it up to my 06 dodge stratus and see if it shows target idle speed.

I remember all kinds of TPS failures doing exactly what you're describing.

Really? That's interesting since I replaced the connector years ago, using the actual Chrysler service kit for it. That still doesn't explain why cycling the key gets rid of the issue. At least with the TPS, I can read it with my old Snap On brick.

Hooked up a DRB 3 to my 06 Stratus today. There is a target idle speed PID that can be monitored.
