What are the symptoms Carlos?

Massive blue smoke at start up and intermittently while driving. Funny thing is though that the smoking seems to go away after I've driven the car long enough to let the ECU adapt. The car seems to drive okay after that point but not great. So thinking that the issue was fixed, I tried to clear the check engine light by disconnecting the battery and then the check engine light comes back on and smoking starts happening again.

The car was intermittently squealing yesterday. The squeal would come and go at different speeds. The car is also idling rough. It seems to be dipping down below 8000 rpm. I can smell a faint smell of burnt plastic/rubber. I am getting the 1124 O2 adaptation CEL codes.

Thanks for the help. Any advice is greatly appreciated.

hi There Carlos

 

Its been a few years.  you probably drive a 991 now!   Do you recall what caused your new AOS to fail?

 

Some AOS units, particularly aftermarket units, are prone to early failures.  Some are actually bad right out of the box.

Thanks for replying!  AOS was purchased from Sunset Porsche.  The car is no  longer smoking. 

I tried removing the oil cap while engine is running, it was tough to remove, but doable. 

It felt like there was suction. 

Is the engine supposed to keep running flawlessly after removing the oil cap?  OR does the idle rev higher OR does it become low and stutters?

If the AOS is working properly, removing the oil fill cap creates a vacuum leak which upsets the idle.
