First off I am new here. I just purchased an 2004 350z two days ago. It currently has a turbonetics kit on it pushing 7lbs of boost. The only other engine mod to it is a kinetix manifold. It is a 6speed manual transmission, and I stalled it a few times in the last few days. The last time I stalled it it started right back up but now it is acting weird. At about 2500rpms it feels like it is hitting a rev limiter and at idle it isn't smooth it is bouncing around about 200rpms. I don't have a check engine light on, however, my air fuel gauge is reading leaner the it is use to. It is reading 10.0 at idle and when i give it as it goes up to 13.5. Before this problem it use to run a little rich like 13.6 at idle and higher as i gave it gas. The car has 51,000 miles. I read the frequently asked questions and it mentioned something about disconnecting your battery if you stall it out a few times and it starts to run weird. So I have done that now and I will reconnect it in the morning. But it also said that it would turn on a check engine light and mine does not have one on. Any help would be greatly appreciated. Other than this it has ran perfectly. And currently it runs smooth up to 2500rpms then feels like it cuts out. I really appreciate any insight. Thanks.

 

vac line?

 

Well I woke up this morning and reconnected the battery and now it runs as good as it did. The top 100 common question really helped out on this one. Thanks.
