THROTTLE BODY SWAP NO CEL!!!!

[kou]

So i did the swap without getting a cel ever. THANK YOU jkuchta for the info.I ordered a new intake manifold, a yaris and a corrola throttle body.Step one was to fill in all the cavaties on the manifold with JB weld then port the opening as much as i could. swapped the chips over on the throttle bodies and removed the epoxy from the idle adjustment screw,then switched everthing over, did a pre adjustment on the idle screw and made a paper gasket which is siliconed in place.

[thebarber]

how much were you able to open up the stock manifold?

[kou]

I ported the top to about 2.4" then i tappered down as much as i could, the plastic is thinner the further you go.the factory opening is 1.75".

[thebarber]

not too shabby

notice a difference then?

[tk-421]

Nice and clean. Very good job! :thumbsup:
I opted for a custom adapter instead of porting the IM. How much did the IM cost? Just curious.

[kou]

There is a difference at all rpms but more after 2250rpms.more engine power with the ac on which is a big plus. my ASStermater says more tourqe than hp.definetly worth the $250 in total spent.

Thanks tk-421.manifold cost $113

Wow that is nice:bow::bow::bow:
this is one Mod i would love too do , but am affraid to do as it might not
be as simple on the 2NZ-FE.:thumbdown:

Enjoy and congrates :clap::clap:

should be the same...only different item on the 2nz is the pistons/rods (and therefore the displacement)?

[cali yaris]

nicely done. I've always thought that this mod, done carefully, is a good one.

Thanks, definitely can't rush this one.

[d1nzfe]

what do u fill up those 'holes' with? the purpose to 'strengthen' the frame for porting?

[Nexus1155]

NICE WORK, very good thinking on how to get it done, as long as you let the JBWeld cure and it stays that is a nice for DIYers. Just hope nothing ever happens where a chunk might come off of that and go into the engine

[kou]

Thanks Nexus.I am not to worried about the JB weld it's now a solid ring.Any way if something did happen engines are pretty cheap.

[kou]

I used JBweld the slow curing type.Mainly to make a flat mating surface for the throttle body.Because of the intake manifold design after porting you have to put JBweld on the inside to get a smoother slope.

[Nexus1155]

Drive a full cycle, usually 80miles on most ECU's and let us know if there are any CEL then? I would love to do this.

[YarisSedan]

Wow very nice. If your gona do something do it right. For the price of the intake manifold its not that bad.

[kou]

No CEL after 2 days and half a tank of gas.
Only have high idle on cold start for 20-30 seconds then its all normal operation.

[Thirty-Nine]

Good to see a port-matching job! If I could do this on the cheap, I'd probably give it a go.

[Astroman]

You would'nt happen to have any pics of the porting do you? I did the TB swap but just bolted on the new one w/o doing much else. (No CEL either.)

[mario98c]

Astroman do you use the corolla tb with the yaris tb chipor you use the corolla one?

[tk-421]

Both ways work. I have a 1ZZ TB with a 1NZ chip, no CEL. Just a high idle for the first 30 seconds or so.

[mario98c]

So all i have to do is put jbweld in all the openings of the intake manifold then make the chip swap then make the idle screw adjustment and install everything up? i am correct?

[Astroman]

I used the corolla TB and chip. Bought mine from FunctionSpec. It had a different part number though than what everyone else seems to be able to find. Mine was off of a 05 Corolla, no chip swap or idle screw adjustment.

[mario98c]

Can you give me the part number if not too much trouble?

[Astroman]

Not at all: #22030-0D030

I found this by searching ebay right now (http://cgi.ebay.com/ebaymotors/04-05-Toyota-Corolla-Matrix-1-8-Throttle-Body-2004-2005-/120458234381). Although I paid about half that on here, but it's the only one with that part # I've found on here.

[mario98c]

Thanks Bro:thumbsup:

[Astroman]

Your welcome! Hope you get one, and if you do please post your findings and results.

Astroman, did you experience abnormalities when the aircon kicks in?

While my car was stopping (with aircon on), i could feel jerking and my car moving forward even i stepped on my brakes..

And did you experience oscillations while driving?

I have the same throttlebody number as yours and have not done any chip swap or idling screw..

Going to try the chip swap soon.... :frown:

[Astroman]

No I haven't noticed any abnormalities except at cold idle startup, but I've only used the A/C once or twice. Once it gets HOT here (which will be next month thru august) I'll check it out more.

I ordered a new intake manifold, a yaris and a corrola throttle body.

Nice work mate enjoy your workmanship :thumbsup:

Is this the 1ZZFE throttle body?

Thank you, and yes it is the 1zzfe throttle body.

So its has been a week and still going great.One cel/code popped up which was a p0171(bank 1 system lean.)This only happened once on a 95degree day with high humidity the AC on stuck in traffic,cel turned off on it's own the next day so i am sure its because of the conditions that day caused the cel.High humidity not good.

Did you do a coolant line bypass on the 1ZZ TB? I did, and I've literally never had a CEL with my TB.
Although it may not be advisable under very cold weather for what I hear (we don't get too many of those down here)...

[kou]

Yes i did,i am thinking about putting it back in the fall.

[kou]

I have had this code before with the stock setup so i am not to concerned.

Kou, i also have the same symptom as yours. AC on, stuck in traffic, CEL on. But my error is p0172(bank 1 rich). CEL went off on its own on the next day.

Now still monitoring what causes this CEL. :confused:

[moh]

i got a TB with part number #22030-0D030 and want to install it next week.
should i do chip swap and idle screw adjustment? and what about coolant bypass?

Just try swapping over first like I did. Didn't need to do a chip swap or idle screw adjustment.

I didn't do the coolant bypass because it can get pretty cold where I live and I don't want any issues. Car works awesome with it hooked up.

Hi Guys,

I had swapped my 1NZFE chip into the 1ZZFE throttle body but after one day of driving... CEL light up.. error code 0172 (fuel trim too rich bank 1)

I reset my ecu, and drove again... and the next day... the same error code came out.... :frown:

These two codes came when i was moving off slowly and with air con on.

I swapped the 1ZZFE chip (part number #22030-0D030) back onto the throttle body and there's no CEL till now. But i could feel rpm oscillations when car was slowing down. By adjusting the idling screw, does it helps to remove the oscillations?

Should i stick to 1ZZFE chip or try making the 1NZFE chip works? :confused:

Thanks everyone! :smile:

[sito]

Any advice, please?

Thanks... :smile:

[tk-421]

Leave the 1NZ chip in. That's the way I have it and it works great.

[sito]

Thanks for your advice, tk-421. :biggrin:

Are you using the 1ZZFE chip with the 1ZZFE throttle body too?

Thanks....:smile:

[tk-421]

Sorry, I meant to say to leave the 1NZ chip on the 1ZZ TB. I made the swap and I haven't had any issues so far, other that a high idle when cold starting the car.

On the other hand, I've heard from some people that didn't need to swap the chip at all (1zz chip on 1zz TB). I have a theory that the issue is directly related to the TB serial number, but I can't say for sure. I tried compiling a list of serials a few months ago, but it didn't catch on. :iono:

With your 1NZ chip on the 1ZZ TB, did you experience any jerking (around 1300rpm) while you were driving?

Did you adjust your idling screw? How many turns did you adjust? Anti-clockwise?

Thanks in advance, tk-421...:smile:

[kou]

Still running great no CEL.

[tk-421]

Don't mention it. :thumbsup:

The bigger TB will increase your overall throttle response. There's a bit on an adjustment required on your part (basically, one needs to be less hard on the pedal). Although to be honest, the throttle controller that I have installed makes that effect much more apparent.

Did you adjust your idling screw? How many turns did you adjust? Anti-clockwise?

I can't remember right now, but I believe it was more to the right (CW) than the left (CCW), but it really should depend on your particular installation. You can adjust it while the engine is on, but don't trust it too much... The ECU will also try to auto-adjust over the next few days. If you don't feel that it's perfect you can always try adjusting it further. Just be careful not to strip the screw! :redface:

i have scion tc tb in my yaris

[ROCKLAND TOYOTA]

i have scion tc tb in my yaris

is it from a Z or R motor???

[kou]

wow thread back from the dead. anyway may car is still running great no cel just a little high idle in the winter months but it is all good.
