Since this is a TSB and not a recall unless they can reproduce the rough idle they won't be able do anything. It's so easy to check though you can do it yourself in no time.

Before: Sometimes when I come to a complete stop and throw it in neutral, my rpms would shoot to 1500ish and back down to normal.

After: Hasn't happened yet.

Review: It definately solved some idle issues I was having.

I tried to get my dealership to look at this on the 04XT but they refused. They just blew me off entirely.

Guess I'll do it myself and send them the pics if the filters have dropped.

If I want to replace the washers, any idea what the part number is? I guess you need four of them, right?

I also had this issue of idling recently. In 5 min. time it was all fixed!
Way better when cold but not much diffrence when warmed up. Both sides were not in the banjos! One was realy lodged tight in the botom of the banjo hole (pasenger side) but with some small plyers it came loose!
I simply reused the washers. Over the years I have never had a failure or leak from a copper washer as long as it was not groved or scratched. I am glad I found this info
Thank you

Did mine today. I've always had a slightly erratic/rough idle. However, my car stalled twice today at idle. Decided to give this a try to see what happens. Both my screens were dropped and my idle seems steadier now. I'll report back longer term. Oh, and if you have a really long socket extension this is a piece of cake. You won't even have to remove the air intake hose on the passenger side. DO IT PEOPLE.

Done this morning. FMIC plumbing made the drivers side hard, but still pulled nothing out to get the job done. 30 min tops.

Both screens had dropped, both were clean @ 43k miles. I wonder what they were designed to catch since whatever it is, it isn't floating around my motor.

Didn't make a difference at all so far. I have an odd issue where the car will raise RPM as I came to a stop (clutch in, foot off throttle), sometimes running up to 2000 rpm and it won't drop to idle until it come to a full and complete stop. Rolling 1/4 mile per hour it still revs... once I stop dead, the idle drops to normal. Been doing that for a long time. My condition isn't what I'd call a "rough" idle, but an erratic, or uneven idle. No pops or misfires.

The other idle issue I had/have, and I won't know until tomorrow AM if it's fixed, is when I remote start the car cold, and after the engine warms for about 5 minutes, the idle pulses. Slow RPM climbs for about 2 seconds, then drops back rapidly to idle, and repeats immediately.

Also, the car, since installing the UTEC, takes like a moment for the ECU to come to life on startup. Key in, ignition,start sequence too quickly and the initial idle was always nasty, or would stall back out. But it'd clear up after the O2 warmed up and idle fine. Or if I wait 2 seconds-ish between ignition and start, it's always fine. The UTEC may be part of my whole issue too.

Brought mine into the dealership to get this done. My vin didn't match the TSB so it wasn't done. I still think I have a rought idle though.
Should I pull them anyways?

I did pull them out of my v7 STi swap and that did make a big diffrence in idle. Even with 800cc injectors and cusco motor/tranny mounts.

I had the errant filters removed from my '04 STi last night. Both had become dislodged from the bolt and wedged into the passage below. I had been experiencing an intermittent rough idle. I had not noticed anything else, but this could have been affecting performance in other areas. I hesitate to say it feels better, because of course even the headlights seem brighter after you make a change like this.

Finally got around to removing these filters this morning, and good thing I did. First off, thanks Peaty for a great write-up, it took me a whole 20 min this morning to do this. Sure enough, when I removed the banjo bolt on the driver's side, the filter was no longer in the bolt but in the recess below. The passenger side filter was still in the bolt, so that was nice to see, nonetheless, that sucker came right out. I wasn't even really noticing any rough idle but I figured, wth, this will be a quick thing to do and glad I did.

I just did this...be sure you have a long enough extension for the drivers side. Otherwise you have to move the wrench close to the positive battery terminal. Unfortunately I shorted out so I removed the negative terminal and continued.

So basically what we're doing is removing the bolt and checking to see if the filter dropped down below? And if it did drop, just remove it and throw it away? Peaty, any reason why you ordered the new parts in your other thread at scooby mods? How come you needed a new union screw?

There is a switch on top of the steering column to turn and off the parking lights, all you did was hit that by mistake:

Thumbs up

I just did this and what a difference. I would constantly have a rough idle cold or warm. My main problem was when I would slow down at a stop and put the car in neutral the car would hesitate do a quick shake and then idle, after taking the filters out everything is smooth. No more rough idle and I feel that shifting is smoother in the lower RPMs Iím very happy thanks for this info.

I just did mine today, BOTH filters were not in the bolt. I don't know yet if it fixed anything but it may have fixed an oil burning problem when the car is cold. I will know tomorrow if it did. And if it still smokes when cold and given gas then i have other issues but we will see.
