2004 hemi pcm replacement
I had a problem with a persistent p0058. Sensor and wiring checked out. So I bought the same part # pcm, used from ebay. Arrived today, pulled the battery positive cable, and changed it out.
Good news, check engine light is no more. Starts up fine, then dies as soon as it drops to low idle. No codes, just won't run at idle. Do I have a bad replacement pcm, or is there something I need to do to initialize it ?
Runs fine with the original computer, but the CEL is keeping me from getting an emissions inspection

The replacement pcm doesn't give me a code.... but it dies as soon as it tried to drop to idle. I don't know what to expect when I just drop a replacement pcm in the truck, should it run?
I expected to have to flash it for inspection. and have a dealer appt scheduled for Wednesday to flash a replacement. Don't really want to pay the dealer to flash a broken one !

You should have bought one from www.solopcms.com where they will sell it at a good price and pre-flashed / VIN matched
But would really like to know if its normal to swap a computer and have it not idle. If its normal, pcm cost plus flashing cost of this one will save me $110 over the solpcms option. I guess I can call the Dealer on Monday and see what they say.

Ebay seller sent me another... just arrived today and I installed an hour ago. Runs fine on this pcm, and no pesky p0058 code anymore.
Only thing, the A/C indicator lamp won't light up.. and the heater mirror indicator is flashing. I read on a forum that if the recirc door is broken, that happens. Mine is removed, I have the replacement but haven't got around to put it in. Perhaps its time to put that door in.
Do I need to have the dealer flash this computer? Its exactly the same number 56029-116AF, which I assume corresponds to the program they put on this thing. My odometer is showing correct mileage, I had assumed it wouldn't because the refurb guys seem to want your mileage... maybe that is for warranty?
