CEL Help: Misfire Cyl. 1,2,3,4,5,6, and multiple random misfires
Anyone know what this could be? Guy at PepB tells me probably need to change spark plugs.
Facts:
'04 6 speed with 53K miles
Running K&N with no resonator
Stage 3 exhaust mod
bypassed coolant to TB
Seafoamed at 45K, intake, oil and gas (did gas alone again a 1K ago)
Low miles for a need for plugs, no? Maybe I fouled them with seafoam. Car runs smoothly. If the CEL wasn't on I woudln't even think anything was wrong. Do plugs need changing based on age AND miles like other maintenance items?
Thanks for the tips guys. Also, what do you all replace with? NGK Iridium? I was told that at PB but I told them I'd refer back to my old trusty forum first.
TY!

I'd try changing the plugs. I'm used to changing my plugs every 12k miles or so in my previous cars. NGK iridiums every 3rd oil change Luckily, they were 4 bangers

Shoot, I hope I didn't!
I mean, I've not fully engaged the clutch but I've never dropped into a lower gear and over revved this engine. My RSX type S wasn't so lucky but it handled it like a champ!
Yeah...seafoamed and never changed the plugs so I guess it's time. Cheapest fix either way. About the random, maybe I'm misquoting what I read...something about misfires out of sequence. I should preface this by saying that I reset the CEL twice and both times it stayed off for about a month. Bent valves would show up again immediately, I would think.
Princely, thank you for the quick response. Excuse my ignorance but what ARE the OEM plugs? NGK iridium?

Tell me about it...all the other transverse engines I've had were 4's though so at least they were all pointing at you. Ha ha...oh well...the cost of luxury I guess.
Anyone else corroborate the plugs needing changing? also...please confirm the stock plugs. Wanna make sure I get the right ones.

Don't know if this applies but check it out. I had a similiar issue in my 5AT, and this has fixed it.....

Good Luck! I thought the same thing, Nope! I only got charged $50, for the 1/2hr it took them to do it. I was just happ not to have the light come on and flash and then off again. Random! Hope it helps. BTW, nice low miles on your '04.

^^^said post seems insanely banal and tedious. I thought it easier to seak the path of least resistance. That and I wasn't sure whether or not it was in there. Thanks either way!
PS...I'm all hyped up ready to stop at the dealer. I get in the car and the CEL is off now. Weird...it was on for a week already. I guess I have a few new ways to tackle it next time it shows.

Hey, FYI- my light came on and flashed 5-8 times then went off. Usually when high in the RPM's, in 2nd gear. I could not replicate it and they said there were no stored codes, after the first visit. Eventually(after this happened 3-4 times random within a week or two which only one time it stored the code of random misfire), it finally happened again, and I stopped by without turning the vehicle off and had them read the code which was random misfire again on a few cylinders(don't remember which exactly). I read another thread awhile ago before I found the link I sent you that said something about the crank position sensor(was a fix for someone else!?).Anyway, hope your dealer can try this and it works. Let us know!!

Hmmm...well, mine wasn't a flash. It was always on cold mornings when it was warming up...and would stay on for a week till I reset it. This was the first time I let it go and wanted to get it fixed and it turned off by itself. I guess I'll stop by anyway when I have a chance. I thought if the CEL turned off the code had self cleared also!? Maybe not?
I think I may do the plugs anyway...since I'm over 50K miles and I'm into MPG etc.

What were the exact P codes that were read?

Yeah, but what are the four digit codes that were read?

Seafoaming is usually a precurser to changing the plugs.
See what happens after the plugs are changed.
This is why some do not recommend the Seafoam unless you want to move to the next step.

when u have missfire on all cylinders what are the chances of having all spark plugs go bad at the same time in an instance ,,, honda spark plugs last up till 105 K
electric or mechanical or head gasket problems would set a missfire code on one or two cylinders even if the cam shaft is broken or worn u would have a missfire codes on one bank wether it's the front bank or rear ..... the additives in the gasoline could kill the engine ( all cylinders ) the computer would register a missfire on cylinders 1,2,3,4,5,6, and random missfire detected ( P0301 302 303 304 305 306 and P0300) at time of the missfire and a minute later if u rev the motor up or restart it the missfire readiness monitor being continous would turn the MIL light off cause the engine stopped misfiring
i worked on cars with 175K and original spark plugs still installed and no misfiring ,, lattely right when they add those additives to the gasoline ( between seasons change )
we've been getting odessys accords and elements with 15000 miles with all cylinders misfire

There is no reason to ever Seafoam a 45,000 mile engine......ever!
I've pulled the heads off of many engines and at this mileage the pistons are just getting a brown tint. There is no appreciable carbon in the combustion chamber. There is no crud on the intake valves or intake tract.
Do not put it in the oil! It is a solvent! It thins the already thin oil. It lowers the HTHS. It lowers the film strength. It does not play well with the seals. Did I mention it's a solvent!
There is no "crud" at this mileage. It would be the same as buying your TL new and adding Seafoam straight off of the showroom floor.
Save this stuff for when you're past 200,000 miles.
If you're going to use this stuff, might as well go old school and use diesel in the oil and save yourself some money.
