Great, so you have the correct ECU. Follow the steps in the thread I posted that showed you where to find the ECU, and pull the blink codes. If you aren't sure how to read the blink codes, you can make a video with your smartphone, upload that video to Youtube, and post it here so we can help you read the blinks.

Another_Si_Guy

Okay. To reduce any error I am most likely going to record it. Just post the link to the video once it's uploaded?

Yep. Upload the video to Youtube as public (you don't need to make it listed, just public), and then post the URL here. The forum will automagically turn the URL into a video, like so.

Okay. Pulling the codes now.

61, 67, 90, unless I'm counting wrong. 61 is your primary O2 sensor. 67 is your Cat. 90 is Evap. Do you see how I read those, with the long blinks being dashes (10's) and the short blinks being dots (1's), with long gaps between codes, and an even longer gap when it's restarting?

Since you already have a test pipe and seem familiar with the defouler trick, go ahead and do that. Afterwards, reset your ECU, and we'll see if that resolves the 67. I started with this one because it's the easiest.

Did you say you already bought an O2 sensor, or have you not done that yet? If you haven't bought one, let's do some more diagnostics there before you do. You'll need a multimeter (if you don't have one, and don't have a friend with one you can borrow, they're like, $15 at Sears or Walmart for a basic one). If you already bought an O2 sensor, install it, reset the ECU, and see if that resolves the 61.

Do you have the original Evap hardware still there but disconnected, or did you remove it when you swapped motors?

Another_Si_Guy

Okay, I am planning on dropping the cat all together pretty soon and throw a defouler on the secondary o2 sensor. Until I can do that I'm gonna have my exhaust leaks fixed. And I to already have a brand new o2 sensor purchased. I bought the car with all of the engine codes present and the engine as already in the car when I bought it. I haven't even had it for two years yet. Its come a long way since I bought it, haha. That being said, I don't even know what the evap hardware is, let alone where it is.

There's the charcoal canister. Excuse all the grime lol.

Don't worry about the grime, **** gets nasty down there anyway. I'm at work and don't have an FSM in front of me, but when I get home I'll try to remember to post the diagnostic flowchart for the evap system. IIRC, there's a purge valve or something that's supposed to be on top of the intake manifold.

Another_Si_Guy

I will check the valve on top of my manifold tomorrow. I really appreciate all of your help through my situation, had it not been for your knowledge I wouldn't be where I am. Anyways, do you have any clue as to what could be tripping my evap code? I read on another post on this page that some guy replaced all of the evap hardware and was still having issues. Turned out he was over filling his gas tank. But there was also another guy with the same code and needed his ecu replaced. If thats the issue I'll probably just opt for a hondata.

There are a few things that could be causing it. Evap hardware being removed with the original engine is the first direction I'm going to point - no need to get too complicated with it quite yet.

Another_Si_Guy

Okay. I'll update you with the whereabouts of the valve as soon as possible. Also, do you suggest that I change the o2 sensor, put in the test pipe and defoul the secondary o2 sensor all at the same time or will I be okay with replacing the primary at a different time then the test pipe?

I'm personally a fan of doing things one step at a time. Start with the test pipe and defouler. Reset the ECU, test drive, see what codes come back. If the cat code goes away, then carry on. If it doesn't, then figure out why it doesn't. Then move onto the primary O2 sensor. Replace, reset, check codes. If the code goes away, carry on to the last code. If it doesn't, back up and figure out why it doesn't. That way you aren't adding the possibility of extra problems on top of the changes you're making. Always tackle one problem at a time.

Another_Si_Guy

Okay. As soon as I have the test pipe installed I will come back with an update. Should I bother resetting the ecu now, or just wait until I have the test pipe installed?

NotARaCist

Wait until after you've installed the test pipe and defouler.

Another_Si_Guy

Will do. I'll be back with updates. Thanks a lot man.

Also, the reason I'm leaving the evap for last, there's a lot to it.



That's the "pointer" page. Most CEL codes only have a few possible causes at most. The evap codes are obnoxious catch-alls.

Another_Si_Guy

Yeah I've heard that from the small amount of research I did.

Another_Si_Guy

I apologize for not being able to get a picture. It was pouring all day today and I didn't really want to open my hood and take a picture. Also, a few updates. I'm having my exhaust leaks sealed up tomorrow afternoon. And I'm getting my hands on a test pipe this week. The test pipe should fix all of my exhaust leaks for good since they're all around the cat. Also, as for the defouler, it's a little difficult to find them. I was informed that they are relatively cheap but the ones I'm finding are like 25-30 bucks. I found one for like 10 but I'm not sure if it'll fit. It says universal Honda/Acura but it also says 04-08 Acura TL.

If you could please tell me if this is what I am looking for and whether or not it will fit.

They're all he same thread pitch, so that one should work just fine. Or you can go to your local parts store and just pick up a spark nonfouler and modify it yourself, since that's ultimately all it is. Or you can look on Amazon, there are options for $3 plus shipping there.

Another_Si_Guy

Okay. I'm really not looking to modify nonfoulers it seems like people had difficulties doing it. I appreciate the input.

Another_Si_Guy

Update: Sorry it's been a while. Progress is slow. I'm still waiting on a test pipe, my friend who said he would give it to me hasn't had time to drop it off yet. I have ordered a defouler and it's on the way. Also, something inside of my cat has begun to rattle. Right around 1600 rpm at cold idle it rattles pretty obnoxiously. Also when I let off the gas and the rpm drops it rattles. And my exhaust smells more like sulfer every day. That's all I have for now. Once I get the test pipe and defouler I will install them, reset my codes and post the blinks once they show up again. Then I will install the o2 sensor and repeat. I'm confident that removing my cat will solve my problem, but I would still like to clear any codes that I have.

cat is gone...

Another_Si_Guy

I'm aware lol.
