whats going on guys....I have a 2011 sedan the last few months every once in a while my car goes into limp mode...but not really, it will allow the rpms to go to the redline, but it takes a while to get there. at WOT it feels like there is a civic engine in this car. So i pull over and restart the car and it works fine again. This happend 3 times in the past 2 days. did a quick search on here no one seems to have this problem. any ideas? dealer said a while ago it was bc of my intakes (BS). the car also has RHFC. Think I should remove everything before i bring it in again?

 

try putting it in snow mode. Are the symptoms the same?

put it back to stock.. if it goes away you know where the problem lies

 

I'm going to...then trade it in for a 335 lol it did this when all I had was intakes. It's going in to infiniti Monday. Well see what happens

 

I had a similar problem in my un-modded 2k9 G37xS --

I twice experienced the car trip into this mode where it would seem like it was hitting a much lower rev limited -- around 2500-4000 rpms, and I couldn't get higher than this .. it would buck and jerk .. I pulled over both times this happened and it would idle nice an smooth while in park, and I just turned it off, and turned it on again after 5 seconds and it drove perfectly.

The second time this happened, the dealership applied a transmission update, and hoped this would solve this problem as well -- no engine codes resulted. That being said, it last happened around 25k miles, and now I have 70k and have not yet experienced it again, knock on wood.
