rough idle after jumping battery

My battery died in my 14 GT. I jumped it off only for it to idle crazy. Fuel air ratio gauge was to the max and the gas pedal would only rev engine up just a bit... help! Any suggestions

Do a fuel pressure test.

The fuel pressure should be 30-45 psi with the vacuum hose attached to the fuel pressure regulator. It should be 40-50 psi with the vacuum hose detached from the regulator.
The fuel system should hold pressure for five minutes, with a loss of less than 5 psi from the indicated operating pressure.
