Please feel free to chime in and comment on this because this is all news to me.

Notice the stand alone EVAP system, On my 95, it had a bulky metal looking EVAP canister purge valve. Also, this one is routed to the USIM itself. (follow the red colored line. The second line goes down into the engine bay and has a **** on it, never seen this before on my 95. Any info on these updates.

See description above. Zoom in of hose w/**** leading to EVAP.



As for the spider assembly, does this look normal to you guys?

-There is one micro-log not being used at all. -
Also one is plugged in but T's off back into the micro-coolant logs.
-Another has a hose attached but wasn't plugged to anything.
-The Throttle body lines should be spliced together correct? Since the 5th gen TB doesnt require coolant.





These coolant lines attached to the USIM. The USIM had a T like fitting that connect both lines to each other which seems like a running coolant system w/return. Do i need to get rid of this for the 00vi? Whats best way?

Here is a 99 Fed spec IACV. It only uses 1 sensor.

the coolant lines are nothing new, every 00VI thread mentions them. Toss them out.
That is a 99.5 IACV, not a 99.
As for the vacuum gallery, can't help you now as I got rid of it completely.
The EVAP system still works on same principle. Run one nipple to vacuum, one to fresh air.
Any other questions?

Do you just cap ever line with a screw or something?

iTrader: (26)

Vacuum lines? Sure, if you want to go the ghetto way. Why not pay the ~$2 and get a box of vacuum caps?

The '99 IACV has no idle-up solenoid for the AC system, there is no '99.5' difference.

Where are you finding a reference to a '99.5' IACV?

shadyonedeath

iTrader: (10)

I didnt know a box of vacuum caps existed....



Alls good. Just need to buy some hoses for coolant and fuel hose. Hopefully my UIM is sealed on right. I bolted up the 5th gen EGR first, loosely (which was a direct fit) and then the front bolts of the UIM in a crossing motion, then the EGR again.

Everything seems to be going smooth, no major modification.



Some pics for enjoyment.

Questions regarding the nipple shown in the red square. What's it for? I've searched and only came across info regarding the solenoid nipples. The Orange stays free to fresh air, and the Swirl valve one gets plugged. Didnt catch what the third one is for.

Is it just another vacuum source for say, the spider assembly/fuel rail?

DAVE Sz

iTrader: (2)

no. It's still part of the VIAS solenoid assembly. Just leave it alone. Of course you could just turn on the car and plug it with your finger to see if there's any vacuum there...
What exactly did you search for? The 10 threads I just looked at all have the nipple open...

Having idling issues. It turns over now with some play on the pedal but i need to keep holding the gas about 10% for it to stay on. Here are some vids.

I did a test run with the MAF only. Im going to put the whole airbox so i can quiet it down and check for vacuum hissing.

wait so you have the air filter flat against the maf and that's it?

Sorry but all I see is a panel filter loosely positioned against the maf. Why you're expecting the car to run fine is beyond me...

MOHFpro90

iTrader: (11)

What do you think the stock intake is? Its just a bunch of piping. Hell, screw the filter, remove it, and test it again. It will do the same thing with the filter, without it, and with or without the whole intake on there.

That being said, check your IACV gasket. Also what happened to the issue with the 1/4inch vs 3/8inch nipple?

DAVE Sz

iTrader: (2)

If the filter element was perfectly flat, it should be different. Since it isn't flat, only a 1/3rd or 1/4th the element is touching the MAF while the rest is sitting away from it letting air go in.

Are the grounds connected to anything? The ones with green tape on them. They look like they're sticking up in the air not connected to anything in the pics.
The hiss is way too loud to be just a small leak...
Pictures of the finished product would b nice otherwise there isn't much to go on...

shadyonedeath

iTrader: (10)

Your right about the filter, ill get on that.


The grounds are connected together to a thick gauge grounding cable, going to the timing chain cover.

Ill reseal the IACV.

brb.

DAVE Sz

iTrader: (2)

take more pics when you get a chance...

MOHFpro90

iTrader: (11)

Yes, but my point is, the car will run perfectly fine with a filter, without a filter, with half of the MAF housing covered, etc etc etc. The filter has nothing to do with the way the car is acting.

VQ30MPG

In the video, it looks like the vacuum hose in the orange box below is disconnected and wiggling. 95% sure it needs to be connected for the engine to run properly and that it's where your problem is.

shadyonedeath

iTrader: (10)

Success! It was the damn tube on the IACV, (who would've thought? i thought it only needed fresh air...) the big one that connects to the 4th gen air box. I reassembled the 4th gen airbox and plugged it in, car started fine, idled fine, a little high but my IACV screw is fcked so...yea.


Now i just gotta do some tuning/tweaks to the setup for my 5th gen airbox.


Pulled 0401 - air intake sensor..
and 1302 - MAP/BARO SW Solenoid/Valve ...wtf is that

MOHFpro90

iTrader: (11)

Damn bro I should've seen that. Yes, the MAF does take into account that amount of air in the A/F calculations.


That being said, congrats.

Does a flutter at the engine shut off mean a vacuum leak?
http://www.youtube.com/watch?v=nQ5vgOX2yk4

I really hope its not something major like the UIM or valve cover gaskets..

Where the hell are the test drive videos? lol

I wonder how much it would cost to have someone install that with all parts provided. I have a auto 99 cali speced I30. Then there is that smog problem.

DAVE Sz

iTrader: (2)

no, it isn't....

DAVE Sz

iTrader: (2)

if you trace back the vacuum hose from the "boost sensor" it will take you back to the map/baro solenoid. In the above picture where the guy circled the hose. here is also that brown connector right next to it. That's the map/baro solenoid. You probably ran the vacuum for it wrong...

I hope you have a 5th gen maf adapter cause the 4th gen maf won't bolt up to the 5th gen air box...

i was planning on doing this.

Unless there's an easier way..

Any word on that flutter at the end of the last video i posted? Happens when i shut the engine off.

DAVE Sz

iTrader: (2)

you mean that whoosh sound? People say its cause of a bad o-ring, the orange one, in the 5th gen IACV. Of course I know it's not cause of that and you're using the 4th gen IACV...

MOHFpro90

iTrader: (11)

His is different from the sound I am getting from my bad O-ring, though it does have something to do with the UIM having vacuum during idle and then equalizing the pressure to atmospheric.

What size hose are you using for the IACV to UIM nipple?

MOHFpro90

iTrader: (11)

No easier way, really. And it should work 100%. Just keep that large MAF O-ring there and it will seal up nicely.

This look right? I heard AJCOOL say something about NOT using a 4th gen FPR with the 5th gen fuel rail...is the 4th gen FPR attached to its fuel rail or more down the line near the fuel filter?



Only thing i did was swap the complete LIM from 4th to a 5th along with its appropriate fuel rail and lines.

MOHFpro90

iTrader: (11)

Haven't heard Aj say anything like that, but I wouldn't remember anyhow.

Your routing is correct, vac and fuel lines are good. Though, I dont know about that FPR on the front rail. Here, check this:

Also, AugustaMoon had a thread (I think it was his) about his fuel setup, Ill see if I can find it for you.

MOHFpro90

iTrader: (11)

This is the thread I was referring to. It seems there is a bit of info on the adapters, but not *too* much. Might help though. Personally, Im not as knowledgeable in this area because I have never done a full LIM swap.

http://forums.maxima.org/all-motor/5...ting-00vi.html

Look around page 3, I skimmed and saw him mentioning some stuff around post 103.

shadyonedeath

iTrader: (10)

I pm'ed AJcool and he said it looks fine. He used his OLD FPR from his 4th gen fuel rail on the return (labeled #2 in pink) and it wasnt working well for him.

thanks for the links.

BUT...according to Pat, if you don't use an adapter, you have to convert to returnless? How much more work is that?

shadyonedeath

iTrader: (10)

Ok, i definetely think i have vacuum leak which SUCKS because i need the car on tuesday and tomorrow is the last day to work on it.

http://www.youtube.com/watch?v=ooY4I6ok_sY

Youtube video says it all. Has wierd chirps as I rev, and theres a hissing sound coming from behind the 00vi.

Product_Of_Korea

iTrader: (8)

Not entirely true.

If you still have enough hose still left on the existing FPR(5th gen) you can just hose barb it together.

I dont have a adapter and ive used the rail on two diffrent setups, running return style setup

shadyonedeath

iTrader: (10)

yea thats what I did. I used the existing barb.


Anyways, the VAFC2 issue is SOLVED. Someone on the .org posted wrong info saying the red wire on the VIAS connector goes to POS+ battery terminal and the green goes to PINK wire on VAFC...NOT TRUE. The Green goes to the PINK wire and the Red goes to a GROUND. The pink wire on the VAFC2 = 12v OUTPUT.

So yea, the VIAS arm activates now.

Edit: I just realized i didnt post a question about the VAFC activation issue. I was having trouble because i followed the wrong directions of some thread i searched for and the wires needed to be switched...this is what happens when the search function fails and results in outdated information.


I still have a vacuum leak, im 99% sure. Even though my idle is like 790rpm~ i hear a swoosh sound when i rev it, and also when i turn off the engine. Various videos can be found on this page.

http://www.youtube.com/watch?v=tEYHJFE_RKY





Possibilities of vacuum leak:

Since the car is making a suction noise when i rev it, and a release noise when i turn it off, it should be a VACUUM leak.

-Valve cover - Is this under vac pressure? or would it just leak oil?
-UIM - I doubt it, car idles very steady.
-LIM - " " " "
-Hoses- im thinking its a hose of some sort thats not snug enough and seepin air.
-EGR tube - My EGR sits a bit further back in the hole, it covers the rear of the whole about 70% and 30% of the front if the front is the Throttle body port. It could be the ring around the EGR tube that seals with the O-ring is not aligned right due the the 70/30 angle.

Can anyone confirm the EGR seal becomes open if the EGR isnt perfectly centered in the EGR port of the UIM?

shadyonedeath

iTrader: (10)

Apparently the hissing is common? Read this thread, its short.

http://forums.maxima.org/all-motor/3...ting-00vi.html

DAVE Sz

iTrader: (2)

no, that's not true. Pink vafc wire goes to the fatter, red wire on the VIAS connector, the green/red wire from vias connector goes to ground. The arm activates cause the vias is now normally open and when you reach your activation, it closes. You have it backwards...
I'd like to know which thread listed this wrong info...

shadyonedeath

iTrader: (10)

but i saw it with my own eyes...when the car is on, its closed, and when it reached its activation, the arm moved towards the firewall. Ill test out your method.

DAVE Sz

iTrader: (2)

its not my method. it's he ONLY method. If it was reversed, you would still see it move when the activation point happens, but it would move the other way. Again, which thread told you to wire up the pink to green/red?
