So I come out of work and start my car as usual and immediately hear stuttering, look down and the CEL is flashing. Shut the car off right away. Restart the car and it was like nothing strange happened. That was two weeks ago and other then that one time the car runs great. I checked for codes, none. Contated Service, they said it could be many things, even low octane fuel could cause that. He suggetsed waiting to see if it happens again. Doing some research it looks like these motors had a lot of left head issues, missing tapping loss of power etc. This was supposed to be corrected in 2012. I sure hope this isn't the same issue. Anyone else have this issue or something similar, any thoughts.
