Need help...
I just did a battery relocation to the trunk. Upon starting the car the car rpms will jump to 3k then tries to die. If I feather the gas pedal for a few seconds the car will then Idle. After that it I rev the car very slightly the rpms will jump to 3k and hang for about 5 seconds then falls very slowly.
Nothing was changed on the tune at all. Any ideas what could be causing this? maybe a ground? or does the pcm have to re learn after being disconnected from the power source?
Thanks in advance.

Also, all your long term fuel trims will have been reset. I would double check grounds and verify the voltage at the front vs at the battery. Injectors work off a voltage scale so if they are seeing less voltage than previously they will be working off of a different offset table.
