Idle too fast after intake install...
I was so excited my fujita CAI came today and i installed it. All went fine, but now my idle seems way to fast. My max is idling at about 900 rpms in drive! I shouldn't have to adjust anything right? I know alot of people have fujita CAI here, anyone else experience this?

i'm not even sure what normal idle speed is for the 6th gen actually, it just seems off, alot faster than before the intake. I used to have a 4th gen max and normal idle for that was about 650 rpm.

900-920 is normal bro 
... BUT
You can always make sure its put on correct... all sides even... no extra air coming out more on one side kinda thing...
Just go over your work again...
If that fails put the stock one back on and see what the idle is and how it feels.. I have the fujita myself and the idle didnt change ... good luck and keep us posted..
P.s. Search for the ECU reset using the pedals etc... Might just need to adapt to the new mod(s)... or you can wait and just drive for like 3 days

My car idled a bit louder and I just attributed that to the extra breathing. Your idle sounds like it's in the right range. Are you confusing idle range with sound?

I have the Stillen CAI, but I too noticed an increase in idle speed. It goes away after the car warms up, but right when I start the car in the morning, it jerks hard into "Drive" and rolls at nearly 10mph which isn't safe cuz my parking structure is a tight squeeze, lol. I just feel that the extra speed is a cool thing to have in CA for stop/go traffic. RPM-wise, it actually stays about the same as stock, but maybe a bit higher i.e. 750 vs. 900rpm

I guess i'll try putting the stock intake on to see if it changes anything. I'm just a little annoyed I guess, my car is completely stock and I just wanted the intake and now it just seems like something is not right. I'm starting to miss my old '97 max, that car responded well to every mod I put on it. The 6th gens seems to have too may complaints and quality issues.

6th gens and 97 max cant compare...
only comlaint i have is that i didnt get a 6spd..
i have PLENTY of mods.. not one problem...
maybe you should take teh advice i told you earlier: IE ... install the stock intake... then try it again before you start to bash the 6th gens...
97 better than a 6th gen??? lol come on man ...

Dayle,
Most cars have some minor complaints and issues. There aren't any here that cant be or hasn't been solved. I wouldn't mix your idling situation with 6th gen quality as a whole. I would ask that you specify what issues plaque the 6th gen that mar its reputation, especially before making a comment like that.

I'm not saying that am perfect but this is not my first intake install and this is not my first maxima. I may well have done something wrong that I have yet to realize, but I do also feel that I am entitled to my opinion, and I do have my doubts in the overall build quality of my present 2004 vs. the 2nd, 3rd, and 4th gens I have owned in the past. I'm not limiting that judgement on cars alone but for all products in general. My current max I bought used only 3 months ago and so far it's been back to the dealer quite a few times, for alignment issues(still not resolved) and tranny issues, and most recently the fuel pump was just replaced by nissan, all this with just under 50k miles on the clock. Don't get me wrong, I love the maxima alot, I'm just not getting good vibes about my future with this car given my most recent experiences. I am grateful however to the org for all the knowledge and support I have gained over the past seven years I have been on it.

dayle, you are totally right , you are entitled to have your own opinions etc... i hope you get this problem figured out... please try what we talked about and see how it feels then...

The target idle speeds for Maxima's 04+ According to the Nissan Factory Service Manual are M/T 625 +- 50 rpm
4-speed A/T 700 +- 50 rpm [in P or N position]
5-speed A/T 675 +- 50 rpm [in P or N position]
These values are checked on a CONSULT-II after running the engine at about 2,000 rpm for about 2 minutes under no load.
Then rev engine [2000 to 3000 rpm] two or three times under no load, then run engine at idle speed for about 1 minute.
4-speed A/T 700 +- 50 rpm [in P or N position]
5-speed A/T 675 +- 50 rpm [in P or N position]

FastMax,
Thank you for your compliments. I really do like these cars. But I can be fair enough, if enough evidence is presented. As of yet, I haven't seen much of a track record of failure, to label it a lemon.

Dayle97SE, I've got 53k on my car now, so far no problems. Hope you can get this issue resolved.

OK, so I took a look at my install job, and started by removing the intake and looking at the throttle body, and from what I can see, the throttle plate does not seem to close all the way, it seems to be stuck open just a hair or too. Being that this is an electronically controlled throttle body is there a way to reset the closed position for the throttle plate or butterfly valve(not sure what it's called) ??

I just installed a Fujita cai on my '07 last week and it is sweeeet.. The only thing is that when I start it first thing in the morning the idle shoots to about 1800 then after it warms up for a minute or 2 it sinks down to about 700-750, right where it has always been with the stock intake. I did do what the SM learning recommendations:
1) Accelerator Pedal
2) Throttle Valve Closed
3) A/I Volume
This process did not seem to change much of anything except maybe dropped my warm idle down by 50 or so. It still idles high when engine is cold but for just a short time then is back to normal and stays that way all day. Throttle response and mpg are improved and my max runs great. I have checked the installation and everything OK.
Has anyone else experienced this idle oddity or know how to fix it?

The first thing I would do it test for air leaks. Make sure all connections are tight and not leaking air. Next, I would drive it around for a few days and give it a chance to get used to better airflow. Sometimes the motor neds a few start/stop cycles to get used to changes. I know this was the case when I replaced my intake manifold and when I had the headers installed recently. If it hasnt settled down in a few days, there is some problem assocaited with the install: i.e. something broke, got disconnected, etc.
There is a way to adjust the idle. It has to be done electronically such as with an Uprev.

Tried the battery disconnect and it did not make a difference. Checked all my connections for air leaks and all is good, hopefully it will just fix it's self. My car runs great except for the 1 minute high idle in the morning.. I guess it hates mornings as much as I do! LOL
I hope someone can help me solve this problem soon, if not then I will just go ahead and get the idle reset after I install my Cattman y-pipe and Nismo catback next weekend.

Oh you are going to enjoy that little addition!!Side note: if you are ever planning on doing headers you probably want to get the Y pipe with the catalytic converter in it.

Funny I'm reading this I installed my Nismo CAI yesterday and founf the car the idle a little lower than usually I got out to grab something from the trunch and it sounded like it was going to stall, wife even said " the car almost stalled" I will give her a few days of driving and see if it goes away. I know there are no leaks I took my time on the install and triple checked everything..Love the sound of it though NICE GROWL..

I already have the Y without the cat so I will put that on. When I talked with Brian last week he said that they are not quite done with the '07 headers yet. He did go on to say that the testing on them are making a HUGE difference and is very excited about them. I am sure that I will go down that route when they are ready and just add a cat then.
Deus, I will take your advice and wait for the ECU to adjust. By the time I do my exhaust this weekend it will have been 2 weeks with the cai and I am guessing that should have been enough time to adjust if it is going to.

whats wrong with a little bit higher idle. its not going to hurt your car..... inn fact it may give you a better 60foot, and a little more response. my buddies gtr making 650 idles at 1100 rpm. your choice but i do believe that it cannot hurt the car.... if you are still worried then take it to the dealer. i dont believe it will void the warranty.

Mine cleared up after a few days but then started throwing codes for idle to high. Then the car started pinging( Pulling timing due to it leaning out) Took it to the dealer to get the idle realinged.. Warranty FTW.

Yea I know I started thinking that a few days ago but it't not under warrenty and a little pricy $520. But if it needs it then it does. The dealer is checking the catylist in the front end of the car? Not sure what this is( Can't be the canister can it) But they said if that has a leak it will lean out the car and cause the pinging. I still think it is the MAF but we will see.. Thanx for the input man.. Every bit helps..
