Default pulling a TON of timing... heat?

Just got the boost creep issue figured out and since I left the exhaust shop it has gotten worse, it wont even crank and idle now, I had to two foot it off the lift. no reason to have to do that with this cam, anyway...

it cruises fine but at any touch of throttle the timing plummits off the charts and sometimes goes even into the negative... my burst knock tables are zero'd and i've buumped up the IAT retard table so it doesnt pull quite so much, other than that, the table looks fairly normal no?? attached are a couple logs of this and my current tune.

just burn the other wire on the other side the same way so they match! Fix your plug wire then go from there! check the plug to make sure you didnt ruin a coil or a plug! Like loney said make sure you are firing! Good luck ben hope ya get i running!

it didnt have a mis or a dead sounding cylinder so I'm assuming it still had spark.

I drove it on the rack, lifted it, welded on the exhaust, and lowered it back down and it was doing this. I disconnected the batt and am letting it sit for a while to reset... maybe it jacked something up that way too... but the burnt plug wire is never a good thing LOL

I probably broke it moving it around, oh well, I've got more in the shop to throw on it I've got the heat boots for the wires as well that need to go on.

sounds like the motor's blown up again lol.

I would say the wire has nothing to do with it. It will still fire as long as it isn't severed. One of my stockers got burnt from my OBX's but still worked just fine.

it was just burned but I felt the inside break while I was moving it around...

right now, it fires right up and dies. I can make it run with the throttle but I hate that BS. and when it does idle it idles at about 500 RPM, I have it set to around 700

and it dies idling up to a redlight...

yeah, I'd say the motors blown again time for something bigger anyway

true, but I wonder why it would have happened from the time I pulled it on the lift, and about 25min later when I went to leave??? IAC does make sense... I though it may be a fuel pressure issue but that looks fine on the guage.
