I was on my way home from the tattoo parlor yesterday and i came to a stop light, stopped like normal and they car felt like it was running a little funny. Light turned green, i hit the gas and the car sputtered and struggled to accelerate. Its an automatic, it shifted hard into 2nd, and 3rd then wouldnt go above 27-30 mph. just bouncing as if it hit a rev limiter in that general area. It was really terrible. i have Stillen Gen3's, Berks HFC's, Invidia CBE and an UpREV Tune, think any of that has to do with it? or any other thoughts?

 

check your maf sensor. It's the things you plugged into the gen3's . Make sure the plugs are nice and tight and that the sensors are positioned the right way and not damaged or wet.

 

I thought it may be a sensor but I wanted some extra input, I thought maybe the O2's buut I've never seem em cause a problem like this, I'm gonna go check it out now make sure the whole intakes on nice and tight and those mass airs are on there good and see what happens. Thanks for a quick response!

 

I did that stuff, made sure everything was nice and tight and had no luck so I called the shop that did the tune and apparently my car went intoo a safemode. Had me turn the car on and off about 5 times and its workin again. Well see how the rest of they day goes. Ill keep this updated!

 

Wow... good luck man. Let us know what happens later, i'm curious what the problem is too. Since some f us have similar prob, or the 'limp' mode, but i think our similarities was Injen CAI, and you've got the Stillen.

 

yeah stupid cold airs. it finally threw a check engine light so i'm takin it to the performance shop tomorrow to have it checked out. It seems fine right now but i'm gonna let it chill till tomorrow and take it straight there, hopefully it runs fine all the way out there

 

If your car repeatedly goes into safe mode that should tell you something. Don't ignore it or something will go boom.

 

Boom goes the dynamite!

 

well this is the first time, if it does it again i may just have it returned to stock and bring it to inifiniti and get rid of it at the end of the year like i planned, not for anything else, just for an S in stead of the X. i'll see how it goes

 

When did you get the hfc done? I'm only asking because the o2 sensors are a pain to get off and have been known to break when taking them off. A bad o2 will cause the car to go into limp mode.

 

Intake and exhaust got done a few months ago hfcs were done about 2 weeks ago. I'm goin to the place that slapped those on tomorrow, they also did the tune, they're gonna help me out
