some sort of spark issue or some serious head problems,

get a compression test done this should help you out a little more!

no it still runs the same when you take those 2 leads off, my friend who is a mechanic said that it sounds like bent valves because there is marks on the pistons where they hit when it snapped a con rod. i will try n borrow a compression tester.
cheers
