I can't remember if I ever heard it before the CAI b/c I got it 1 week after a got the car. It has been happening randomly for about 8 months. It has only been recently that I have been noticing it more and more.

I have had my HKS SRI in for about a year know and it happens just about every day still. I have gotten used to it know, but it still freaks anyone riding in the car with me out of their mind!


do you think our cars have bad valve seals, I am saying maybe the valve seals arnt sealing enough on the intake side and a little gas vapor is coming out and detonating near or in the manifold......thats just a ROUGH thought......

it took mine about 2 months to hear it but i will put back my stock one see if i can solve this isue

for TSB's go to .. www.alldata.com

they have every TSB for every car

Yeah, but you have to pay $ to get to read the bulletin. I believe when I quoted another forum, I included that this was a fix that was not directly listed in the title of the bulletin, but was a problem that was corrected by using an update that included the ecu flash update. When I call the dealer I am going to ask him to look into numbers 03-020, 02-041, and 02-026. I will see what they have to say.

So, where in this do you see the details of the TSB? This is EXACTLY what I was talking about when I said they only give you the titles of the TSB's and their numbers. Nowhere in here is the detailed descriptions of the things that are fixed by the TSB.

I also have the same issue. I am calling Honda on Monday morning to schedule a visit. This is what I am going to tell the about:

(from another forum site)
"Just a note....

Went in for some warenty issues yesterday as I discussed. And suprise, suprise, I now have a software update for my ECU. The software flash is referenced under a Bulletin for misfire diagnostics after start up. So a Tech might not think it relevent... so ask them to look for SW updates that referance this. Somtimes manufacturers will correct multiple issues with an update but only referance 1 issue in the bullitin(Legalities).
I have put on about 400 KM since the update. and cannot reproduce the occilating tourque we were feeling... i belive the misfire diagnostics was to radical and was effecting timming causing the surges in torque. My kudos to Rob Walker and Maxwell Anderson @ Barrie Honda for there efficiency and help with my problems."

Hopefully this takes care of it.

As I said, I think 03-020, 02-041, and 02-026 are the ones to look into. But hey, since you guys seem to think I am an idiot who can't navigate a web site, go ahead and trust the headlines. For me, I'm eventually going to call the dealer and talk to someone I trust there and see what they have to say. After all, we are dealing with speculation, since no one on this site has yet to even try to get the update.

[HondaMan]

Well, I guess somebody will get around to getting this update (if possible). I listed the TSB info to be helpful so people didn't have to go search for that info on that website, not to show you are an idiot. Relax dude!

[Bicho6]

definitely needs to relax..

First, let me say I'm sorry. I will agree with the both of you that sometimes I get a little wild. I just don't like it when I have to repeat myself in a place that uses a written history of conversation. I can apprecaite that Hondaman did a copy and paste on the list to save me, or whoever, time and to help out fellow EP'ers. But as I said in the first place, we are looking for an update that is not listed in the main title. You have to pay

I didn't think that what I was saying anthing was that difficult to understand. We are all fairly intelligent people. Going back on the point of written conversation, it is even easier to mis-read or interpret something that was written incorrectly, since you can't hear the tone of voice. I was not pissed off. I was confused as to how that list was supposed to help me, based on my previous statements.

[sleepin02si]

I decided to look at the TSB titles for both 2002 and 2003, since we are sharing this probelm on both models year vehicles. There is one title that references the ECU and is listed on both cars.

Does anyone know what a DTC is?
