what mods do you have? how about carlitos?

Hey mate!

I didnt a CEL at first, but dealer was able to pull the code anyways, so maybe you can get that looked into anyways.

As far as mods, only the ones on my sig. However, i took all the parts out from my Z and its bone stock now and still have the issue.

This seems to be something bigger in my opinion, you have guys bone stock and mod cars with the same problem. One question, everyone with this issue has had a reflash done to their ECU? I know I did a reflash.

No reflash for me or carlitos

However, it does make sense that there might be some problems with the ECU. How can you have the failure now, turn off the car, and then have it working again like nothing happened? Doesnt make sense that dirty maf sensors and/or throttle bodies would do this! I would expect that if my mafs or throttle bodies are dirty, the issue will happen everytime i turn on the car, just like what i have experienced in other cars. Only thing i can think of is the "start cycle" or whatever its called. If this is the case then maybe it makes sense for this to happen. Ill have to start counting how many times it takes turning on the car and have this issue happen lol

Just wanted to chime in and report the same exact issue in my '13 z. Stillen gen 3 intake and fi exhaust. It goes back to normal after a few reboots :/ definitely feels like limp mode.

Damn... this maybe its a problem on the 2013 Z's... Well my friend i think this is the solution... The last thing that the dealer work on my car was cleaning the throttle bodies and re-calibrate them. I pick up my car las Friday and for the moment the car are working like new... Pedro leave his car on the dealer yesterday to do the same process. I hope that problem dont come again.... So get you car to the dealer and tell them to do the same process.... Clean the throttle bodies and re-calibrate them... maybe that is our issue.

Hope you can resolve this soon!!!
