Hello Honda-tech, I was wondering if anyone on here can help me diagnose what is wrong with my 2001 ITR. Before all this happens my car was running fine. Here is how it came about:

About a few months ago, I took the ITR out for a drive and hit V-tec a few times. I didn't do any hard launches but just taking it up to v-tec normally. The following day when I went to start the car up, it made some loud rattling noise during cold start up then when the car warms up, the noise would slowly go away. I couldn't diagnose what was wrong with it so I took it into a car shop. They told me it was my catalytic converter and that it was broken. I thought it wasn't that big of a deal so was going to wait to get it replace, as it wasn't my daily and I don't drive it all the time; only take it out once in a while. Over time, the noise disappeared and I didn't hear it anymore but then started noticing that my car was lagging when I take it up to higher RPM especially when it hits V-tec. It almost feels like the car is choking. I've been reading and hear that a damaged cat. will cause significant lost in power. So, just a few days ago, I decided to take the cat. off to see if my cat. was clogged and to my surprise the cat. itself was hollow and all the insulator inside the cat was gone.;leaving me just an empty cat. I then went ahead and decided to take off the whole cat-back to see if any of the insulator was stuck inside the exhaust pipes. The pipes looks fine, but when I got to the muffler and shook it, I could hear rattling inside it. I was able to get all the rattling that was inside the muffler out but those combine were small and seems like there should be more that still stuck inside, but I shook it as hard as I could and there wasn't anymore inside that I could get out. (I don't know if during those times that I hit v-tec if the insulator few out). After all that, I put the cat. and the exhaust back and took it for a drive but, V-tec was still lagging and choking when I get up there. I don't know if my muffler is clogged up and I need to get a new one. The exhaust system is an apexi WS2. Please help me! There is no check engine light.

Thanks.

 

disconnect the exhaust at the "header" then drive it. report back.

UPDATE: I took off the mid-pipe just before the muffler and took it for a drive and it still lagging like before. Once it hits 6K RPM, the car chokes until about 7.5K then it goes. Anyone know what could be causing this? Thanks

 

Spark plug???

 

Check the vtec solinoid screen for build up. Bad Dizzy too?

 

Anyone on here have any other suggestions of what could be causing this issue?

 

CHECK OIL LEVEL?

 

Oil level is good. Just changed it not too long ago.

 

Are you getting any CELs flashing or on?

 

faulty vtec solenoid?

 

I had VTEC lag so to say when I was tuning my own car and wasn't being aggressive with timing. Like 300RPM after engagement it took off like a rocket ship by comparison lol. Just a bad mix switching tables high cam low cam being a noob at tuning. If you're on stock ECU IDK then.

 

i was suprised this wasnt the first post.

 

No cel is on. Still running on stock ECU. I barely drive this car and I don't know how this could have came about. My first impression was a clogged up cat. but that wasn't the case. If nothing else the car is in storage for the winter now. In spring, I will just take it in to get it checked up. I'm still a noob when it comes to diagnosing issues. Thanks for all the posts.

 

When's the last time you gave her a good tune up, plugs,wires cap and rotor , Even check the little clips on your fuel injectors,

 

Fuel filter,valve lash adjustment

 

Hello,

The weather was actually a little nicer this past weekend, so I finally got a chance to work on the ITR. I changed the spark plugs and replaced them with OEM ones as well as new plug wires (NGK). I also changed the V-tec solenoid gasket and clean that whole area out and then took the car out for a test drive and the same issue still persist, however; I did noticed a little improvement but nothing significant. I was able to take a few clips but, the clips doesn't really prove the point as if you were actually in the car looking at the RPM climbed. I will post the clip up shortly so that everyone can see. Hopefully, someone can help me diagnose this problem. To me the car lags from 6k-to about 7.K and the from 7K on it takes off. (IDK if you guys can see this in the clip, when I do upload it up). But please offer your help!

Thanks

 

Maybe a slipping worn clutch? Bad gas? Worn old ignition?

 

Hey guys, here is the link to a few crappy runs of my ITR from 1st gear thur 2nd. Please let me know if you guys know what is wrong with my R.

Was that video with the exhaust fully reconnected? I would suggest a cap and rotor with the plugs and worse you just did. If you have the ability check your fuel and oil pressure. An easy way to check blockage in an exhaust system is use a temp gun along the exhaust and look for large or abnormal what changes through the exhaust. For instance, with the vehicle runnning, 430 degrees before the cat and 220 degrees after the cat.

 

As stated above, need to monitor fuel psi and oil psi during drive cycle.
What are these pressures at idle?
What are these pressures at cruise?
What are they prior to vtec engagement, and when engaged.

Do you have access to another complete distributor ? Possible coil failure although doubtful, its worth a try and swapping distributors is easy. Just make a scribe on your dist. housing and on head prior to removing so when swapping back it goes exactly where it is now.

Sounds like your distributor bearing is on it's last leg.

 

Could someone please verified for me to see if this is the correct OEM part # for the Type-R distributor: 30100-P73-A02? I am trying to find one to replace my old distributor to see if it will solve the problem but looks like Honda/Acura don't carry this anymore. Can anyone tell me where I can still get a Brand New OEM distributor? Thanks

Some info in there. I guess they are out of production, sounds like the gsr TD-87U distributor might still be available to buy new which from what I read will work?

 

Does anyone on here know for sure if the GSR Distributor will just be a direct fit on the Type-R without any modifications. I just want to make sure before I move on to that route as I can't seem to find a brand new Type-R distributor. Also is TD-87U the part # for the GSR Distributor or is there another # for it. Thanks
