Alright guys, I need help and am at a loss of what to do. If you want to get straight to the issue that I'm seeing, go to paragraph 3. Let me preface this with a little bit of info about me and the car and then I'll go into what the issue is and what I've tried.

I had a 2012 mazdaspeed3 two and a half years ago and went fully bolted with e85 tuned by Purple Drank tuning. I have had some experience and never really had any issues with it because I was very methodical and took great care of it. So, fast forward to today, I have convinced my brother and two friends to all get Mazdaspeed3's. One of them, my friend Brandyn, has had non stop issues with his. It is a 2010 (non tech) Mazdaspeed3 mica red. He has had nothing but issues with it because of the way he and the last owner drove it. We know it has had a motor swap in the past few thousand miles by a shop when the last owner had it. It was supposedly swapped with a 60k shortblock. First thing is first, he did not get it tuned and we found out he had a full catless turboback, cpe TIH, cold air intake, hpfp internals, and some motor mounts. As much as my brother and I tried to convince him, he did not tune it and drove it like he stole it. He was on a Cobb stage 2 map. Turbo seals blew, so we replaced with a used ko4. Next the clutch and slave cylinder went out and he took it into a shop and spent an obscene amount of money getting that fixed. Next, after a lot of convincing and three months later, we convinced him to get a protune so he got a protune and was on the base map from Purple drank when something happened.

After a week on the protune, he was driving to mcdonalds and as he pulled up to the drivethrough, there was a loud BANG (sounded like it came out the exhaust), and then the car stalled. After trying to start the car again, it turned over and cranked fine without any strange sounds but it would not start. Next, we brought it to my garage and inspected. We found there was fresh looking oil around the valve cover and we pulled the spark plugs. The plugs in there were completely burnt and one had some oil on it. None of the plugs were showing spark so we replaced all four spark plugs. Then we tried to start it, and it started for a few seconds then died. So next we got and installed all new coilpacks and then after checking his accessport we saw code U0100 so we uninstalled and reinstalled the accessport with the protune on it. We cranked it and it started right up! One problem, however, is MISFIRE CITY. We could hear it and feel it misfiring like crazy so we turned it off but never saw any codes for misfire. I have no clue what to do now because it does not start unless it sits for a few hours and when it does start it misfires like crazy until it just dies. Spark plugs are gapped correctly 0.028-0.030. Anyone have any ideas? Maybe do upstream o2 sensor next?
