Weird Check engine light Code 11?

So have another problem? with my 87 325is project car. I am having a Check engine light that comes and goes. I have a 153 ecu. Reading the code means turning the key to the on position. Anyways it should flash a code of 4 numbers. I have had other cars how you got the check engine light this way. Anyways its been showing up some then it will disappear. Driving does not really change. Car have feel like it has a slight hesitation. But here is a video to see what I am talking about. Stays solid from the end for 5 mins straight. Tried stop test and same results.

I don't think the stomp test work with 153 DME. You need a 173 DME for the stomp test

Yeah thats what I thought. Why I would just turn the key on and watch it blink. But it only blinks that code. When it goes away at random the light just comes on and does not blink.

That is not a code. It is possible that you might have a loose ground somewhere or an intermitten vacuum leaks.
