Just recently got my db2. It idle high due to no set screw in tb. I put one in today and dropped the idle to about 1000. Just left my car idling for about 5 minutes and it threw a cel 11. Looked it up and couldn’t find anything definite, did see on another write up that the ecm… any idea guys??? Thanks!
Your sure its an 11? That code would point to your ECU. I would try driving it for a while with the CEL on and see if it goes away on its own. Alternately, you could disconnect the battery to clear the CEL and then try driving on it for a while to see what happens.
I always love that first few weeks with a new (old) car. IDK if I prefer glaring issues I can just fix, or a car that’s running great that can suddenly gets an issue 
Positive it’s 11 and that would be the ecu. I’ve been driving the car for about 3 months now and this is the first time. It went into limp mode. While I was up to speed I shUT the car off waited a few seconds and released the clutch to start it again and it went away and started driving normal again. It’s only happened twice which have been in the past few days.
