Sup guys,

So my car has been misfiring and throwing (I believe 1301-1303 code) ill have to double check. I did the 60K service, replaced the spark plugs, timing belt etc and the light still on. later on my friend pointed out that the ground wire that connects to back of the block was disconnected and he warned me that maybe the coils are burned. anyone experienced anything like that with their Evo 9 or perhaps knows what could be the issue?

Thanks guys
