Help what have i done

[GIMPEESS]

Well i got in my car this morning and went to start it and it wouldnt start unless
i put the accelerator on then it wouldnt idle. I then realised i had left the wire in the plug to get fault codes off the ecu. i took it for a drive and it drives fine just when i stop it stalls and then when i start it again it wont idle. Ive tried pulling the battery to reset ecu still the same. What have i done have i killed something.

You have to get it to relearn the idle. Disconnect the battery again, then reconnect it. Turn te ignition to the on position without starting it and then move the the gear shift lever into each gear for 20 seconds each. Put it back into park, turn off ignition, start the car, rev to 2000 rpm for 10 seconds, take your foot off the accelerator and shut off car again. See how that goes.
Also, just check all your fuses first just to make sure you haven't blown one of them.
