I'm still screwed.

OK I changed my o2 sensor 2 days ago with NGK one.

Now the misfire is still there , well still code 1 this time.

The misfire is annoying and it happens randomly.

Well I got these suspected culprits.

- Dizzy cap and rotor
- Rocker arm o-rings
- Clogged fuel injectors
- Clogged EGR Valve

/rant. hah! What a day lol.

Clean out your egr ports. How are the spark plugs and wires?

Wires and plugs are new. clean as a whistle. Yeah I will do egr cleaning for sure and also check my injectors for blockage.

SP - NGK Platinums
SP Wires - NGK Blue
Oil in plugs - No
Valve adjustment - 2 months ago from Honda

damn lol.

I don't like the fact that you are running platinum plugs on f22 engine. maybe it's just me. try putting some regular ngk zfr5f-11 plugs in. make sure that your pcv valve is good too. and with your engine at idle, pull off the vacuum hose that connects to the fuel press. reg and see if any fuel are coming out from the reg. just for shits and giggles cause I want to get rid of that process. thanks.

I'm tackling a misfiring problem as well, so I will monitor your progress. I've also replaced quite a few things in the hunt.

Can you test with a known good O2? Like from someone else car thats not having that problem?

[wed3k]

its hard to kill a o2 sensor...

timing is good right? and how is it misfiring? under idle or load?

[Accordlx]

Check for crack intake manifold also vacuum leak,

Guess what lol.. Thre culprit was the coil wire is shortening out. So what I did was change my SP wires and the coil wire. Hopefully that was totally it.

Timing is good.

The misfire happends under 2500 rpm whether on cruise or going after a stop light.

I guess it's ok now.
