Ok, i disconected the battery and check engine light is gone. The problem with the throttle is not engine light, it is that when i step on it it just gets in to "neutral" mode and it doesn't work.
I will update my powertrain control module when i fix my door So i should go to auto zone to read my code? Do i have to go to chrysler dealer to reset module? Does anybody know where is the best place in San Diego to do that?

And if i really need that reader, can someone give me the link to it, because i have absolutely no idea what are you talking about

Thank you
