mornin' all, just wonderin if any one has ran into any problems with the injen long tubes. i have been running into problems after heavy rain or a car wash lately. throwin p2a03 code with ses light on and trying to narrow the problem down. any help would be great and thanks again guys also i did explained more in the tech section.

 

After searching around, other ppl had an exhaust leak in the cat and he fixed it and everything is normal again. Check your cats

 

it can either be your o2 sensor, or your MAF sensors, or an air leak. check for leaks on the intake. i threw this code and it was only after i found out the middle bolt in the top of my intake manifold goes all the way through into the manifold. after putting some teflon tape on the bolt and tightening down again, as well as using MAF cleaner on the mass airflow sensors. the code went away after dissconnecting the battery for a couple of mins.

 

What im wondering is though why does this only happen with wet conditions? i really am trying to avoid the dealership but this has happened to many times and being bugged out after i was car or heavy rains is starting to get to me lol. ill def post on monday what they said so maybe this can save somebody some money down the road. thanks all and any more suggestions over the weekend would be great.

 

So went to the Nissan and they basically told me nothing. They are going to change out the 02 sensor but who knows if it will fix it. They def were not convincing they new exactly what the issue is. Oh we'll I guess we'll find out if it fixes it.

 

Let us know if it fixes it.

 

just quoted me $549 bucks to fix it! If i knew exactly what the issue was i would def do it but they arent possitive that this will fix the issue. Dont really feel like throwin that kind of money at it if it wont fix the problem. what do you guys think? this is really irritating and i want my car back lol. also they said maybe putting my factory intake back on it would fix the issue but who knows i doubt it because it happened when i first got the car and they replaced one sensor and it went away until recently when it gets wet(something is getting wet). thanks again and any suggestions are def appreciated!

 

also shouldnt there be a way for them to test each sensor and find the exact issue? just seems crazy!

 

Is your Injen CAI mounted low? There's a much higher chance of water being "sucked" up by your filters which could inhibit airflow or cause problems?

When I go through a carwash, I notice that everything in front of the radiator is wet, so if I installed Injen CAI or Stillen Gen 3 CAI, they would get wet. It doesn't help if your CAI is mounted low in front of your radiator where the water drips down. Try checking your filters after a car wash and see if they are wet. If they are, there's probably your problem right there.
