....I did remove the A/C coolant hose from the radiator and that spilled a bit, but I wouldn't think that could have damaged anything. Anyone have any ideas? Thanks!
If you had disconnected an AC line, you would have a massive spray of high pressure refrigerant that would have rapidly cooled and created fog and ice. What coolant line did you disconnect? The Radiator itself is has just engine coolant hoses going to it. In front of the Radiator is the combination AC condenser and transmission cooler; connected to it is a pair of lines for AC and Transmission fluid. In front of that is a small power steering cooler.
The hemi has a hydraulic fan behind the radiator, lines from the PS system would run to it, and if you disconnected it, fluid would drip from it, it would be the Commanders special hybrid hydraulic/power steering fluid that you can only get from the dealer.
I thought the '06 did NOT have drive-by-wire, the throttle was connected to the pedal via a cable. Not an electronic throttle body.
The ETC warning lamp is the Lightning Bolt over the venture with the butterfly plate inside it. Is that what you saw when you say the ETC warning lamp lit?
I have had the electronic throttle body go spastic on me in the past. Usually, on an extremely cold morning, like way below freezing, and goosed to much throttle before the motor warmed up and I got all the symptoms you described. I just had to shut the engine off and restart it, and the ETC reset itself and ran fine.
