It's possible the replacement throttle body was bad out of the box, it does happen.

You can also try resetting the system by disconnecting the battery cables, touching them together for 10 mins or so to drain the power out of the system, then reconnect the battery and see if that helps.

Before replacing any parts, I would get the codes read again.

 

Also, IDK what codes or how many, but there was a case where one of the connectors on the PCM wasn't seated properly; causing limp mode and ETC.

Hey, I’m having the exact problems with my 07 dodge charger, did you ever fix it or figure out what was wrong?

 

Im having the same problem and need help myself

 

recently experienced the same problems. I had my throttle body replaced and then the PCM, fixed the issue

 

You don't have to press the pedal. Just turn the key to ON, wait til lights on the dash do their thing, turn key off and remove key and wait 10 seconds. Turn back to ON and wait for the lightning bolt to go away and start the engine. That's the throttle relearn procedure. As for the check engine light, once you've fixed the throttle body problem. Disconnect your negative terminal only for 5 minutes and it should clear your CE light. If not, you'll have to use an OBD2 scanner to clear it.

 

On my Chrysler 200, I had throttle body issues, I replaced it and still had issues and a friend helped me change intake manifold gasket but the etc light still appeared and I had to change the pcv valve. All the gaskets were worn and needed replacing but I replaced the pcv valve and throttle body and the gaskets for both and the intake manifold gasket. Hope this helps

 

I found that replacing the throttle body with a Dorman part and the accelerator pedal as well made any issues go away. Make sure the plug is nice and clean, put some dielectric grease in there.
