Injen Idle Issue?
 

I installed my Injen instake a couple days ago and there has been a few occassions where the car would just stall. Once while moving.

The idle seems to sit at 500 rpms for a bit, then sometimes would dip below that and just stall the car.

Anyone know how I can correct this? I've driven it for well over 200 miles and it happened to me this morning.

Check for vacuum leaks.

Also did you pull the negative battery terminal?

I read somewhere on forums from a credible source that disconnecting the battery doesn't do anything. The ECU will re-learn itself in a matter of 10 or so minutes regardless of being unplugged.

As for idle dipping I had a similar problem on my stock intake once before I switched to Injen actually except when it dipped it shot back up after a second and never stalled. Could be an isolated occurence but as Ranatsu said you should definitely check that everything is installed correctly. It's always possible you got a bad intake too.

The ecu learns rather quickly I will say, but I think it can only compensate 15% long term learning and an additional 15% on short term so in total 30%.
Now assuming you had it adding 30% fuel all the time and you fix the problem and changed the intake and now it needs to pull 60% it can't do that fast enough..

This is just an extreme example. I personally pull the battery cable because it takes 1 minute and the ecu can start from nil rather than starting from my old learned values.

Hope this helps.

As far as stalling goes, make sure your connections are tight and not loose. Also make sure the black rubber tube is pushed inside your intake all the way.

Now once all those are taken care of, reset the ecu and start over and let it relearn.

a question not about the idle dip. but do you guys have a bad rattle at WOt around 5k it sounds like its coming from the air box and im not sure how to fix it, ive tightned up every bolt but it wont stop! help!!! ps this intake with ECUteK from visconti is awesome!

Probably the lever to prop the hood up rattling on the air box. If so just put some foam tape around the part where it hits the air box.

so did anyone get this problem fixed?

I thought I was the only person having this issue. Mine is having the exact same issue so I just reinstall the stock one until I can be bothered having another go with it.
Next week I'll try it again, injen were no help to me, speaking of welds I just went and had a look at them and noticed that there is a little hole in the weld near the MAF sensor and that can't be good. I'm going to get some exhaust paste and put a bit on it to see if that helps! Let me know if you find another fix too!

this is how I fixed mine:

I've seen quite a few Injen intakes show up on the for sale section.
