AGREED. The only time I've seen a bad ECU was on a 12+ year old Dodge Stratus. However, I've heard tons of people having their ECUs replaced and the problem persist (not in the FRS/BRZ, other vehicles).
The crankshaft position sensor would definitely be causing issues like this with rough idle and potential stalls. The sensor must be just a little off or something because with a real bad sensor you'd get problems starting and misfire codes (and noticeable problems accelerating). Then again, this is a brand new car so maybe a bad batch of parts from OEM? However, why the ABS light stays illuminated is also interesting. Those are pretty unrelated!
I figured the car would have at least one FYP, something minor hopefully. This isn't too bad, the 06 Si had tranny problems and I am glad ours does not (*knock on wood*).
