That looks like a VICS screw failed in your cylinder... It actually bent your plug causing the misfire. I am 100% sure it is that. Happened to 3-4 of my friends.. all the same problems..
It is really important you...
It is true that the LSD is pretty weak... But on normal use.. I don't think so. It usually gets killed when too much wheel hop gets in play. The solution is to weld it to reinforce the casting so it can stand more "agressiveness"... Like hard accelerations, intense gear changes...
See what it's...
First you need to remove the plastic bracket that holds the wire loom that passes there.. You have two M6s that hold them in place... You have to break the lower one and get working on the rear motor mount..
You should use a jack and a wood plate to sustain your motor and to be able to align...
Maybe a quick research on 02 sensors and headers should help you out! A lot of info as been displayed here, as well as good how-to's and how-not-to :)
Experience is the best thing you can get!
Well sure you can adjust your e-brake cable but you must first be sure that your rear brakes ARE braking... You can try to fast-adjust your brake shoes by letting your car in neutral in a down slope (making your car back up on neutral) and pull on the e-brake 2-3 times...
For the important relation of weight on your wheels and tires, I catched this really interesting article on JTuned:
