If any of you guys could help out that would be great.

Last week my car went into failsafe mode twice, once on Thursday and then again on Friday. Out of nowhere the car would just die and it would say Failsafe . I would turn the car off and then start it and it would start normal. I have not taken it into the delarship yet.

Today as I am driving, I am stopped at a red light and the car dies on me, I am like WTF! . I tried starting it about four times, nothing. Finally on the fifth try, it starts and the engine light is on. I get to a parking log, park the car. Pop the hood, nothing looks loose and no leaks that I can tell. I then plug my X-cal 2 to read the DTC's and the following three codes came up P2104, P2111 and P2135, does anybody know what these codes mean?

I've had my C&L intake and Alternative Tune on for about 10 months and have not had any problems until recently.

Any help you guys can provide would be great.
