Hey guys.. got a little problem, and can't figure out what to do.
I've had my Weapon R intake for about 4 months now, never any problems. Now all of the sudden my CEL is on and my car is idling weird... ex: sometimes after putting it into neutral it will drop below 500 and come back up to about 1000 but never stay steady, it sorta bounces around between 700 and 1500. Every now and then when I have started it, it's actually stalled.
Now I took the whole thing off, re-installed it, made sure all the seals were tight. I reset the ECU by pulling the fuse trick. It seems to be running a little better, but the CEL is still on.
Anyone have any ideas?

Thanks!!

 

Don't know if this is your problem BUT most likely it will be. I work at a Nissan dealership and we get alot of guys come in with Sentra Spec Vs with CAIs. They all usually have the same symptoms as you do: Runs rough or stalls, CEL "on" or lack of power. The oil on the filter is sticking to the wire thats inside of the MAF sensor causing the your problems.

 

after reading a number of other posts that's what it does seem like it could be. does anyone one know if there is a way to prevent this? is this something that will happen to everyone?

 

if that is your problem just make sure you switch it back to stock before taking it in to the dealer.
