Haven't got a clue about the long ft1 but your idle is a bit erratic and the spark advance will increase and decrease with it, the question is why?
The reason I'm suggesting you run with the MAF disconnected is this:
If you disconnect the MAF and the car improves then you know that the problem lies with the MAF, it's either:
if you then clean it and the fault goes problem solved and if not you know you have to replace it.
If disconnecting the MAF makes no difference then you know the MAF is OK and you have to look elsewhere.
However, if you clean it without disconnecting it first then you can't actually rule out if the MAF is faulty. If the cleaning works then great, the MAF was just dirty but if it doesn't then you still won't know if your problem is due to a faulty MAF or something else. If the MAF is faulty, cleaning won't help.
So, if you clean the MAF and the fault is still there you might then think (possibly incorrectly) that your injectors are faulty and get them removed and cleaned which will cost quite a bit only to find that the fault is still there and end up still having to replace the MAF as well.
Unplugging the MAF only takes a couple of minutes but will certainly confirm if the fault lies there or elswhere which cleaning won't.
Hope this helps.
