    Greetings !

    Please i have an question with regards to connecting up the battery .

    In a hurry/by mistake , i left the key in the ignition barrel in ON position and then connected up the negative battery terminal (positive was/remained connected) which then obviously powered up electrical system instantly as i put the terminal on the battery .

    Not sure if i might’ve done some kind of damage to the ECU or other electrical modules by doing so ?!

    Car started up fine , and all the electrical systems are working . No immobilizer problems either which i thought it might’ve happened .

    Chasing cylinder 2 misfire but unsure if it’s the coil pack (pretty much narrowed down to the bad coil pack) or i might’ve possibly damaged the ECU ignition driver by doing the above mistake with the hooking up the battery with the ignition ON ?

    Any help/insights to this would be much appreciated !
    Thanks
