2002 Durango R/T stalls at idle

[Trex20165]

I replaced the thermostat & housing, bypass hose & radiator hoses on my 5.9 engine. All the parts were genuine Mopar parts. After reconnecting the battery, the speedometer flipped all the way to the right. When I started the engine, it stalled. It starts and drives just fine however, it will not idle. Took it for a drive, the speedo corrected itself however, it stalls as soon as I let off the gas pedal. The only plugs I disconnected during the repairs were the Alternator and the A/C compressor. I re-checked and both are connected properly. Any ideas why it stalls and will not idle? I also checked for an error code on the odometer and it displays "P done".

may need a iac (idle air control motor) did you hook the ground back up on the stud for the ac tube hold down bracket

Re-checked all the connections. Took it for a drive and after a mile or two it is now idling just fine. Not sure what happened but now it is running great. Thanks!

For some reason when the battery is low on charge, these Dodge engines will not idle. Happened a couple of times to me when the battery was drained and needed jump started. You have to keep the throttle up off of idle until the battery has a little charge.
