Welcome to this big family, prescottcharger
First of all, owner's manual. Official Dodge site has the manual for you to download.

Choose your year and model, the link provided should already be '06 and Charger but better double check it.
Are the signs in the attachment similar to yours?
Manual says the Electronic Throttle (thunderbolt thingy) lights up should go to dealer asap.
You can wait for some more experienced members chime in as you read the manual.
