Re: idle missfire?
I'd clean your grounds and unplug the coils (then plug back in) one by one while engine is idling if possible. If the idle doesn't change, that pack is the issue.
Re: idle missfire?
ill try the coil one by one today
Re: idle missfire?
anyone had p0306
Re: idle missfire?
oil going into the coil pack and plug was the issue. cover gasket leaking
