[QUOTE=SPLNDID,Dec 17 2005, 09:09 PM]I would be very interested in finding data that could, or could not support the use of injector cleaner every 3k miles or so.
This thread has got me thinking about checking the injectors every now and then.

I'll definitely get the part number. The dealer told me that since Honda is paying for the new injectors, they want the old ones sent back, presumably for analysis. I'll try to get a digital photo of the old ones, but I don't know how much, if anything, that will reveal.

Thanks for the good wishes. I'll be back with you all on Monday.

P.S. As for injectors getting clogged or worn out, I can only offer this bit of anecdotal information. I've got an Acura Integra with 172k on it and has never had any maintenance on the fuel injectors (including fuel injector cleaner) and it still runs as smooth as a sewing machine.

I agree.

Preventative maintenance causes its own set of problems.
I spent a few years as a technician at a major manned space flight provider. The policy at the time was to constantly check stuff...
Sometimes we cause problems by diving into stuff that is working perfectly fine. However, there has to be a decent procedure for checking and cleaning injectors.
I don't have rough idle problems yet, but I can definitely tell you that my engine is running rougher under power. One of the things I suspect is that the injectors are not flow-balanced.
Perhaps the best action for me to take right now is to run a tank or two of injector cleaner from Chevron.

Success! (I hope!) The new fuel injectors seem to have done the trick. Idle is very smooth with no "puffing" noises from the exhaust.

I don't know what the part number and my dealer didn't seem to know either when I asked. I did look at the old injectors and they looked pretty clean on the outside (unlike the one pictured earlier in this thread). I may have just picked up some really bad gas during the Hurricane induced shortage here in Texas which fouled things up.

At any rate, I'm just glad to have my S back in working order.
(...and not staring at that %^$#@^ CEL!)

Quick question guys, when im 'puffing' mode and car has been idling for > 10 mins, does the exhaust start to smoke badly?

Many thanks

No smoke out of my S.

I aways let my S idle in between runs when autocrossing (20 minutes or so at a time) and I did this when it had the misfire at idle, never any smoke.

I don't remember reading or hearing about any other misfiring S with smoke.

Congrats, it will probably last at least as long as the first set.

I think I spotted some white smoke the very first time I noticed a CEL. It was a pretty cool morning compared to what I'd been experiencing, I had driven a lot of highway miles the day before, and I was about a block from the hotel I was staying at. The "smoke" didn't continue and I never had any more when it threw the subsequent codes, just idled really roughly once it was warmed up. It had been "puffing" a bit before that, however, so I'm pretty sure it didn't just start then.

Smoke typically means that something (oil or coolant usually) is getting into the cylinders. Good luck.

Geo02S2k

Thanks. I hope at least. The first set lasted 30k before the CEL popped up. I picked up the car with 24k on it, so I'm hoping I can keep it going a little better since I'll know what is happening to it.

Damn... Oh well, will have to delve into the engine after X'mas to see whats going on then...

Thanks guys
