okay...i just installed my z-tube and stillen intake and took the car for a spin on the freeway. 15 minutes into driving all of a sudden all the warning lights on my car turned on and it seemed like the car stalled or the computer in the car reset. it stayed like that for about 30 seconds and just when i pulled over to a side street everything started working okay again. what can cause this???

 

search. it's happened many times before.

 

you must have a clamp loose behind the maf somewhere. i just installed mine last week no problems at all. double check your clamps

 

it hasn't happened to me again, but try gunning it till fourth or fifth gear and put it on neutral when you slow down....

i did a search on the boards and it seems like alot of other people have had the same problem. it's actually scary when your on the freeway and it happens!

 

this doesnt sound good at all. another reason I didnt go that route

 

I have been running with the Z tube and Stillen Hi-Flow Air Box combo for over a year without any issues. The isolated stalling issues, which I have read about, were all related to the true CAI's such as AEM, Injen, etc.

Be sure to recheck the 2 clamps at the MAF/Z tube and the Throttle body/Z tube connections. Also, be sure that the emissions hose connection located at the underside of the Z tube is properly clamped, as well. A few people have forgotten the emission hose connection.

 

+1.

 

A faulty install causing problems is a reason to not go w/ a certain mod?

 

Not so much the faulty install, its the part of the install thats faulty

I've read too many people stating the same type of problem while
driving

 

yea definately not that it may be a fauty install, but the problem people run into is that with a CAI, too much turbulent air rushes in when you are going past 40mph and left off the gas. The MAF doesn't know whats going on, and the car stalls. It only really happens to the 6mt, but there is a way to stop it. There is a deflector you can install so that it prevents that turbulent air from coming in. I have an injen cai, and I've already got used to it. The first day it stalled a couple of times, and then I remembered reading something on the forums. I'm not sure why it would do it with a stillen though. Isn't it like a short ram setup??

 

My friend, I can assure you that the parts themselves in noway cause any type of stalling; unless we are talking about a defective part. One of the reasons Stillen went w/ a short ram w/ ram air type effect is to prevent issues like stalling. One side effect that I had since day one is that when I start the car (I have an automatic), the RPMs rise higher than they normally would before dropping down. I was told this was normal on automatics w/ intakes. The fact that you read about this too often means that many should not be installing their own parts. Volks FTW !

 

I don't own a G35 yet, but from my experience with other engines, this is unlikely. The engine should have a decent fuel setup even with the MAF reading incorrectly. On my car now, I frequently disconnect the MAF sensor and drive around, tuning the fueling based on manifold pressure and throttle position.

This being said, it is still possible, as I know the my car would struggle and fluctuate rpms trying to idle, sometimes dying, without the MAF. This stopped once I fine tuned the MAP/TPS fueling. If my big clunky GM engine stalled a few times because of this, it is more than likely with a revvy engine like yours.

I just don't see airflow issues with this intake though. It seems like a very efficient design, with smooth flow.

 

is this problem on only the 6MT or on the 5AT too???

 

I have the Stillen intake w/z-tube combo install on the car for more than a year too. I redline the car and drive it hard all the time no problem at all. Your MAF might be damage or get dirty when you install the intake. When I used to owned a 1995 Nissan Altima my car stall too because of the MAF being really dirty.
