Okay so Im throwing a bad EGR code. Ive been searching on how to clean the EGR. Im still not 100 percent sure what the location of it is, But Im guessing I know where its at, and that I need to drill through it in order to clean it out.

Now I would like to skip all that, cause it seems like it would take me a day or two to complete the process.

Ive also been searching on other intake manifolds, and came across other intake manifold, such as a Skunk 2 intake mani. It says that there are gains and what not, but how would I go about installing that. Would the ECU have to modified in order to get it to work. Or is it a direct bolt on?

Any info on it would be great.

Also I have an extra mani off my h23a1, I could take that one apart and rebuild it at my leasure, but would it bolt onto the h22a?

 

The h23 manifold is not compatible.

I have seen a write up with pics on how to clean an accord egr. Try searching for it if you haven't found it already.

I am not 100% certain but I do not believe that the sk2 im uses and egr valve which is why it isn't carb certified. In order to make the cel go away with it you would have to use a p28 or modify your current ecu to not check for it. (This is all an educated guess and I may be wrong about part or all of it.)

Alternatively you could purchase a euro-r manifold which does utilize an egr system or you could modify or change your computer to not check for the egr and just block it on your current manifold.

 

Man how hard is it to modify the ecu not to check for it.

Regaurdless it needs to be cleaned or replaced. I do suffer from 3k hesitation. Ive done searching and found the appropriate info on HT to clean it.

 

On the OBDI cars usually you can clean the EGR valve and that will stop the code from setting. This might be true on the OBDII cars too.

The H22 & H23 intake manifolds are the same and can be swapped out no problem.

As for the EGR, there are basically two parts to cleaning it completely. The first is to just unbolt the valve (located behind the dizzy) and clean it out with carb cleaner. This works for most people & usually sorts out the CELL code.
If you still have a problem, you can do the second stage, which is to remove the EGR port caps on the manifold & clean them out. To do this you need to drill & tap each of the caps, and knock/prise them out. They will then need to be re-sealed when you reinstall them.

no

 

actually i'm not sure about USDM. If they are the same as JDM, they will not work. Trust me, when doing h23vtec, i wanted to keep my h23 intake but it was not even close, really.

The plenums are the same

 

the h23 non vtec mani most definitely does not bolt to an h22 head. the plenums will swap, but that egr ports are down in the lower half anyway.

last time i cleaned my egr ports it took me about 2.5 hours. I pulled the manifold, hosed it down with carb cleaner, rinsed it out, the drilled the ports out and ran some stiff wire and carb cleaner through the ports, then tapped the holes, put bolts in so i can clean it on the car in the future. then bolted it back up.

I think you're confusing the plenum with the entire intake manifold. The runners will not interchange, the plenum will.

 

Hmm, sorry if I was giving duff info then , I was just going by the Helms manual which shows the H22 & H23 manifolds as the same.



I could've sworn my engine builder swapped in a H23 intake manifold onto my H22 build when the first one was found to be cracked

 

Yeah, I'll just back up the people that have already said it: only the upper half of the manifolds are the same (plenum and IAB plate), but the lower section with the runners is different because the heads are different.

 

Thanks, I think Im just going to replace it with an upgrade. Probally would be easier. Its getting to cold to be hanging outside playing with my car.

Would someone mind telling me what tapping screws mean.<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by v4lu3s &raquo;</TD></TR><TR><TD CLASS="quote">

Tap = used to thread unthreaded holes or clean up/change existing threaded holes.

Die = used to put threads on unthreaded studs or bars. Also to clean/modify threads.

Tap and die set:



The taps are the drill bit-looking things and the dies are the donut-shaped things.

 

been there tried that a h22manifold will not bolt up too a h22 head
i tried it.... its a no go

 

so I guess you have to predrill the hole, then drill the hole again with the tap.<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by Hawkze_2.3 &raquo;</TD></TR><TR><TD CLASS="quote">

Exactly!
But don't use a drill on the tap itself, chances are it'll just spin and strip before the threads are secure. Use a wrench (i believe they are 1/4") or a crescent wrench if you don't have the fancy t-handle tool. Take your time and the threads will turn out much stronger. Also make sure you use cutting oil. motor oil will work but cutting oil is better.

 

But how do you get the tap to stay stable?

 

it helps to not have meth head shakes i guess. you just put the tip of the tap in the hole and turn it same as a screw, it takes some effort once it bites into the aluminum.

 

I got a Sk2 IM/TB and my car doesn't idle right. It's partly because of my crappy Indiana weather, and the it also needs to be tuned for this... so says my mechanic. It should run with a new IM but just watch out.

you are better off with an actual tap handle. its hard to get a tap straight with a crescent wrench but it can be done. you can get a cheap one at sears.

I just use my left hand to hold the tap wrench straight and my right hand to turn. taps are brittle so you want to make sure you keep it straight while you are turning. I usually turn it in a few times and then back it out a turn as well to "break" the chips that its making.

 

Okay sO I got another question in the way of intake manifolds.

WIth the Iavc, Ficv, and the Egr off an h23a1 intake mani fit the h22a?
