Heck, Hemi, it's been doing this for a while now, I've checked codes at least 5 or 6 times, none yet. He had the darn machine hooked up while it was happening. But maybe he did not have that value selected to look at while it was happening. I think they are hesitant to call Cals folks, maybe some sort of pride thing? Dunno. If they have not gotten a response by tomm. am, I'm going to insist (nicely) that they do so.

I just on kept driving it like I stole the car until the code appeared on the screen.
The big helper was the stereo system, which drained that lame battery by Mopar.
Have not look for a code but look at the voltage going to the TB sensors.

Dude, what is a Tuberculosis sensor? I think you mean TPS-Throttle Position Sensor?:p
Yes the newer Chrysler vehicles use an IAC stepper motor. AFAIK the older computer controled carbureted and possibly earlier throttle body injected vehicles had what they called an IAS sensor (Idle Air Speed).

TPS is correct but getting to the point, TB=Throttle Body (TPS) Sensor (P0123 code) is not the culprit of this problem.
I have experienced the same symptoms it seems – the idle stays at whatever you were running at prior to engaging the clutch - could be 2,500 or 3K or whatever… Then once you come to a complete stop, the idle drops to normal.
Edit: I got no cel.
I found that it was caused by a vacuum leak. I blew one of the smaller hoses off that connects to the large one on the intake near the throttle body.
I’ve never heard of an intermittent or self healing vacuum leak though so I don’t know if this is the cause of what you are seeing.

OK. That's what I thought. The code P0123 will set no matter if it's the sensor or wires though. I just thought he meant it wasn't associated with the circuit all together.
Just spoke to the service guy, says I have to bring the car in and leave it for the day so they can at some point during the day, when they have time, they can hook up the DRB(?) and leave it running for 45 minutes or so. Then they e-mail the results to DCX.
I'm not sure what they are going to get out of this.
And to clarify the code issue. Total time that the car has been in this stuck mode I would estimate at about 50-60 minutes over the course of the last three months. I have checked for codes every time. I'm going to ask the import kids in the speed shop across the street to keep an eye open, since the service guy says the car just goes into the bay, nowhere else. And of course, record the mileage. Trust but verify is my motto.
If they can't find anything(which is likely with it just sitting there) tell them you want them to hook up the Co-Pilot. It's a datalogger which will record everything the PCM sees. It has a trigger button which you carry in the car with you and when you experience the problem you hit the button. It will record 30-45 seconds before you hit the trigger, and a while after. It has enough memory for 3 triggers, and when you finish, just take it back to the dealer for them to download it to the MDS and analyze. They can also send the file to STAR(engineers), etc. They should easily be able to find what to look for.

As with the last post, that will work.
If you need the phone number for the service bay here, they can tell the mechanic how to locate the problem.
When he hook up the DCX version diagnostic plugger (I don't have the name for the unit), he scan the TPS (sensor) voltage and found it dropped from normal parameters.
Just now took a trip. when I parked I got out and fiddled (technical term for poked and prodded) with the TPS connector. Idle dropped from 1100 to 850-900. Nothing world shaking there, just more info others to verify if they have this conditon. When I came out and restarted, rpms were normal for maybe two minutes.

co-pilot no worky on srt4 for some odd reason. At least it didnt work on mine
