just got my nitrous kit installed (n.o.s kit) and the car is running like sh*t. i have'nt even sprayed it yet cause of what its doing. when i accelerate the car its not as responsive, and it starts to sputter as it reaches redline which then leads to the check engine light to flash ! the only thing i could think of is that it may have a minor leak in one of the intakes ..??

??? any thoughts???

 

i would take it to a shop to have it checked out before you spray it...

 

yeah man, but just the fact that its having these problems makes me wonder about the shop.... BTW the installation was done at (speed shop) in miami.

 

its probably something stupid that an inexperienced shop would do. we see this all the time.


dont spray the nitrous until you have someone else check it out.

 

COUGH COUGH ^^You should have drove to see the man ^^ You'd be spraying right now!!!

 

i probably would of if i knew any better....


COMMON I KNOW SOMEONE ONE HERE HAS HAD THESE PROBLEMS OR SIMILAR ONES?????

 

check the intake and make sure the plugs are installed/reinstalled correctly

 

It sounds like an air intake or vacuum leak to me.
I would check the air intake tube to make sure it was re-installed properly after they put the nitrous nozzel in it. Also make sure the nozzel has a good seal around it.
Also check vacuum lines around the air intake tube.
There is one that plugs into the air intake.

If it is sucking air into the air intake tube after the MAF sensor, it will run just as you described because the MAF isn't registering the additional air that is flowing into the intake.

 

just checked and it looks like they were reinstalled correctly.... i think the problem my be that it has a tiny hole where the right fogger's connected (btw it an 07 so duel intakes.) is that logical or does it not make any sence???

 

Just like garym said, if air is getting into the motor w/out being read by the maf, it will run like crap. Sounds like you/the shop drilled the hole to big...fix that and report back

 

Any air getting in past the MAF will cause problems, even a small hole or leakage around the nozzle.
As GolfinZ said, seal it and get back to us.
You can put some electrical tape over the hole and see if that makes it run better.
Then make that shop replace or fix the air intake tube they messed up.

 

alright cars goin to the shop tommorow at 9am il let you guys know if that was the prob.... and then hopefully they can strap it on the dyno and see how my air/ fuel is with the 100 shot of nostradomas lol

 

I bet you it was one of those ZEX kits with the switch thats ran off of the coil to determine where WOT is at .. here's what i say .. Keep It Simple Stupid... kiss it! Just use a freakin micro switch!

 

no i have an n.o.s kit.(blue)

 

well just went to the shop to check up on the car and i think they found out what the problem is but not certain....

they said the jets where f'ed up and it was only giving a little bit of nitrous and a fu#k load of gas,so maybe spark plugsgot fouled.....

so they just ordered new jets ... let you guys know in a bit..

 

That doesn't make sense because in your first post you said you haven't even sprayed the nitrous yet.
If you had never sprayed before it started running like crap, how would that be the problem?
Are you using a DRY kit?

 

yeah it doesnt make sence lol i forgot to mention they sprayed it once to test it out once the install was finished... but wait till you hear what the problem was ...

 

Ok Everyone Feel Free To Give Me A High Kick To The Face Once You Here What The Problem Was.!!! When I Thought The Activator Switch Was Off It Was Actually On Causing It To Miss Fire... So Now That The Problem Was Figured Out I Wanna Spray It And I Dont Have Any Juicy Juice(i Wasted It All Perging Sence I Couldnt Use It!!)


Feel Free To Flame Me By Any Means Nessasary. Lmao.

 

LMFAO. SPEED SHOP!?!? Why does every 350z down here go there for the install. Good to know it all went well... Watch that switch!!!

 

Hey, at least your man enough to admit it was your fault.
I'm glad it was a simple problem like that and you only wasted some juice, and not your motor.
Have fun bro! Nitrous is a kick in the A$$ when set up properly.
