    2004 towncar hot restart

    It's a 2004 towncar signature.
    It will perform a cold start just fine. During the summer, and a multi stop trip, it will start but not stay running.

    We can hear the RPM drop so low, the battery light comes on, and it stalls. We can keep it running by holding the the throttle.

    Temp sensors (coolant or air intake) are probably having issues.

      Could also be a sticky/dying idle air control motor. I'd expect a code scan to tell you if the sensors are dinked.

        you'd think... If they aren't responding to change, but still hold about a 2K ohm load on the circuit, they won't trigger the code.

          Live data monitoring would tell the tale. Don't know if you can just jam a voltmeter in there to monitor without fancypants tools. I've fried OBD2 brains before by accident. The old stuff was largely uncaring about such nonsense.

            I have this happen sometimes. Drive for a good long time. Turn car off an fill with gas (just to give you a time frame) and restart and stall. I should datalog a HOT restart and see whats going on.

              If you have an OBD2 scanner that has a monitor function, you can check what the PCM sees vs what the actual temps are. If they're +/- 5%, they're good. If nothing ever changes or they are way the hell off, change the sensor/check the wires. I had to replace the pigtail on my 93 to the coolant sensor because the wires were all kinked and crapped out.

                Somewhere I have an OBD Bluetooth adaptor. The android obd app should read it then. I'll just have to find it
