Well I put it back to stock yesterday and it still has a rough idle and it'll die sometimes. I guess I should run the stock tune for awhile and hope it just fixes eventually?

 

Maybe disconnecting the battery will help.

 

Remove the negative battery cable for 20 minutes to reset the PCM. Some folks have mentioned turning the key to the start position for a couple seconds to drain any power left over, but Im not sure if its necessary. It doesnt hurt. Do that and it will take a few hundred miles for the computer to relearn all the parameters.

I assume this problem had started before you started messing with your HIDs and getting all those DTCs that you mentioned in the other thread?

 

yeah, it was after I installed the XS tune for the first time. So I should reset my pcm, the run on stock tune for a few hundred miles, then I can retune? I miss my performance tune already..

 

That is the route to go. Hopefully you'll be up and tuned again soon. Good Luck.
