For those with the swap, is this absolutely necessary? The throttlebody I got came without one. Not only that, but I don't see anywhere it would have hooked it's hose to, just the bolt holes for the canister itself. I don't get how it would even work, as the throttlebody looks like it functions identical to the 4th gen one. It stops at "closed" and has a bar going across to stop it when it gets to the point of being fully open. So I don't get it



Also, just double-checking, but I can use the 4th gen TPS on this, correct?

 

what canister are you talking about? the vaccum actuator for the fast idle cam caca? Tell that crap "be-gone" you dont need it, lol. You its only gonna cause you to have to hold the gas for a few seconds at start when the engine is cold, on a cold day. So you judge if you need it or not. Down here in FL it never bothered me not having it. On the 3.0 I never had to hold the gas, even on cold days. On the 3.5 I do, as I dont have an IACV. So you deside sir :-)

 

Well I'd prefer not to have to hold down the gas at all. I like my car to work as stock as possible. I'm still using the 4th gen IACV, but I don't want my throttle to be sticky if that's what the canister prevents (similar to the coolant routed through the 4th gen throttlebody).

 

Oh, btw:



Notice the canister and hose on the throttlebody just to the right of the throttle cables? That's what I'm talking about.

Oddly enough, there's no hole on this throttlebody where the hose would hook up to, no hole for the support bracket of it near the throttlebody's opening (both these holes simply don't exist...there's a "spot" for them, but no hole; the hole looks like it was simply never drilled from the factory). Also, the 4 holes on top of the throttlebody for the canister to bolt to aren't thread, either So even if I were to put a canister on, I don't think I could get it to work.

 

Only the '00-'01's had that style, the 4th gen's fast idle cam was built into the tb using coolant pasages, I was going to attempt to attach the 5th gen style onto a drive-by-wire 3.5 tb, but gave up, it would be near impossible, on that throttle body it would be much easier though.......... But yes, you can use a 4th or 5th gen tps on that tb.

 

So the throttle stop canister was indeed for cold-start idle purposes? Why doesn't mine have one, then? It doesn't even have the spots/holes for it, let alone just missing the canister and hose.

 

Actually on the 00/01 tb's that had it it would 'tap the gas' for you every time you started the car, hot or cold, as soon as the engine starts the vacuum signal pulls in on it and it is no loger touching the throttle. The throttle pictured is a pathfinder, as far as I know the canister only came on 00/01 tb's

 

Actually it's an 00/01 throttlebody pictured. That's Irish44j's car and he does not have a Pathfinder throttlebody. I'm like 99% sure mine isn't a Pathy throttlebody, too

Now when you say "tap the gas", do you mean it would simply push on it for a second and then let go, or what? And during cranking/startup or after that?

 

Sorry I was a bit confused and didn't really look at the pics that well.

When vacuum is not applied to the canister (engine off or wot, but wot wouldn't matter anyways) the plunger pushes out on the litle gold part pictured with the hole in it causing the tb to be opened just a little more, a second after the car starts vacuum reaches the canister and retracts the plunger and the tb closes.

 

I don't get what the point is, then Seems like a replacement for what the 4th gen IACV already does (except just at the instant of cranking the motor), which I'm using, so, I guess it's ok that I don't have it.

 

Maybe this is why 00-01 rev to 2000 at start up?

 

tatanko-

so i've installed the 00vi a couple times w/ 2 different 5g TB's, one w/ the canister and one w/o it.
from my experience:
so my setup is a 4g lower IM, 00vi, 5g tb, 5g IACV (attached to the TB), and 4g TPS.
first time, i had a tb w/o the canister, and i had mad idle problems, which i don't know if it was b/c of the canister missing or not, maybe i had a vacuum leak, either way, i had to go back to school so i disassembled and put it off for a later date.
now, the setup i have is a 5g tb w/ the canister, and it works perfect. keep in mind i'm using a 5g IACV (i had to cut some of the plastic off the 4g harness to plug it in) but it works perfectly, idles start up over 1k and around 600 when warm.
if you're using the 4g IACV, it might be different. but that's all i have to share and hope it helps.

 

Interesting, aznsap. I guess I'll just have to throw it on and see, huh?

It still blows my mind how this one appears to have come from the factory without it, though, and if that's the case you have to wonder how it could possibly affect drivability.

Just needs some cleaning and the TPS swapped over and it's ready to install :

 

What's all that JB Weld for

 

A pile of leftovers. Didn't you notice the patched up hole inside the inlet of the throttlebody? I JB welded both IACV passages shut.

 

I have a 5G TB with that canister and hole if you need it.

 

I'll let you know, but hopefully not. I shouldn't, anyway.

 

according to courtesy parts.com the idle speed plunger was only available in oo. o1's did not have this feature .. intresting..

 

Interesting, indeed. Must not be "necessary" then. Thanks again for the throttlebody, by the way. Hopefully installing it tonight when I get home from running some errands, and I should have your plate shipped out tomorrow.

 

Hope the intall goes well! post your before and after results..

 

It really doesnt do anything..I had it on my Pathfinder TB and took it off...it plunges closed when it sees vaccum and when it doesnt see vaccum...It shuts when it seens vac.

 

Will do! Once I get it on and make sure it's working properly, I'm pulling it back off and possibly doing some porting work to it. I'm also going to fill in that little "recess" at the bottom of the outlet side meant for the IACV's air to flow through (already filled in the port, but I want a perfect circle on the outlet, it's probably better for airflow this way).
Seems like it. I guess I'll see tonight, won't I?

 

here's a better pic..

 

Good for future reference to anyone who finds this thread later.

 

Ok, now I need some help. Bought the proper bolts, have the throttlebody bolted on, but I'm running into a few problems. First of all, I have NO way of securing the throttle cables. There is absolutely nowhere to bolt the bracket down and have the cables even remotely tight. Obviously I can move the bracket a little bit in terms of the tightening nuts on the cable "sleeves", but not enough to mount it anywhere on those bolt holes without rotating it, I don't think. See pic:



Luckily I have what should be the 5th gen cable bracket coming from Dave B, but I'm not sure when it will get here, so I need a temporary fix.

I also have other issues like needing to T a certain vacuum line since there's no more throttlebody port for me to use, and I need to loop the coolant lines together now, but big deal. Easy stuff.

 

Use the 3 bolt holes that are to the right of where you have it right now, it shouldn't pull it too much so the cables wont start to strip.

 

The picture angle must be throwing it off, but, those bolt holes are way IN FRONT of where the bracket is. Looking at the picture I can see why you think that, though. In the mean time I've drilled a new hole in my bracket to mount it on a hole near the coil pack closest to the throttlebody.

 

You have like an inch still to adjust with the nuts and then you can get some good pliers and pull the 2 tabs back to tighten them even more.

 

Bending the tabs has been done twice already. They are like impossible to bend now. The inch isn't going to be enough, either. I'm simply going to have to rotate the bracket clockwise a little and mount it using a long bolt to that hole I mentioned earlier near the coil pack. It's not rotated TOO much, and the cable is still straight into the "arms" of the throttlebody, it just isn't perfectly straight coming out of the "sleeve".

I also need a bigger drill bit. The hole I drilled earlier wasn't quite big enough

 

Ha sounds like fun

 

Put everything back on real quick and started up the car. I have one TINY (one of those really small like 1/16" or whatever) vacuum hose not connected, otherwise the car idled fine between 1000 and 900. Not perfect, though, it would waver between 1000 and 900, it wasn't constant. That vacuum line is probably the reason, though.

I also forgot to loop together the two coolant lines that went into the 4th gen throttlebody and got some coolant on the floor. Oops

 

Make sure you dont have any air in the coolant system. Run the car with the radiator cap off.

 

I'll do that in the morning. I just finished putting everything back together. Car runs and idles like a dream Better than before, actually.

But get this: the throttle is SO TIGHT that it actually feels like I'm pushing on a heavy clutch when I push on the gas pedal. The throttle isn't open at all, either. It's just that initial "push" to get the throttle open and from there 10% to WOT all feels normal. It's just that first push...it's weird. Hopefully the 5th gen throttle bracket will cure that. I'm assuming it's because I have the throttle cables so tightly wound (not as tight as you'd think, but they have an abrupt almost 180 in them).

 

Good to hear everything is up and running.. Definately get that 2k tc bracket in there..

Hopefully i can get my ooVI installed soon!

 

Soon, sir. Your adapter plate will be on it's way tomorrow

 

it's probably rubbing or the angle the cable comes in is weird. just use the 5g cable bracket.

 

i took the hose off and then used the set screw behind it to set my idle to any rpm i desire its that easy

 

I don't think it's rubbing. I also have it coming in at a straight angle, I made sure of that. I think (like I said in an earlier post) that it may be because I have the cable so tightly bound together. It comes out of the firewall, pretty much makes a 90 degree turn towards the passenger's side, then does an almost 180 into my bracket, then another maybe 45 to the throttlebody. It's not rubbing on anything, I know that.

I'll be getting a bracket eventually. Dave B has had it on order for me, but it's been on backorder for about a month now with no ship date in sight. I also have a WTB thread in the 5th gen forums but no one has shown up.

 

I would, but I don't have any of that
