Yes more info is needed. The correct ECU for the 94-95 gt's T4MO and j4j1 for the cobra. Make sure that's accurate first.

Second. Automatic chip inserted in a manual ECU? Possible?

My car was originally a gt but I replaced everything

What differences does a cobra have instead of gt for the ecu
In the engine bay? Better cylinder heads, slight taller lobes on the cam shaft, 24lb injectors.

So since I dint see you write what injectors you now have on, if your using the cobra ECU with only 18lb injectors and also only have a 18lb calibrated mass air flow, you might be off somewhere.

I would check your spark plugs wires are connected to the correct orientation, check psi for fuel, make sure timing is correct. And your injectors and maf match to the ECU.
