Not sure if this has to do with the code but when lightly on the throttle, below 2.5k rpms, car jerks/lunges a lot in any gear. cel will stay off for 200 miles then come on and sometimes go ff by its self. looking into alternators if the sensor doesn't fix the problem.

 

If you do end up having to change the alternator don't get the OEM one. Go with a PA performance or Power Bastards or any high output alternator and never worry about it again. The stock alternator does not provide enough amperage for these cars, especially if you add any aftermarket audio or other electric equipment.
