Hey /o/, need some help.
My 2.0 VI gen Accord is having some trouble at idle speed.
Basically the problem starts soon after starting the engine, it shakes when it's at stop, or when breaking and approaching idle. It was paired with a check light pointing the fault at the main o2 sensor.
O2 sensor has been replaced, same with spark plugs and the wires, but apparently the poor idle problem is still there (check light doesnt show up anymore) - that's what the mechanic over the phone said.
About 6 months ago the car had a floating idle speed problem, that was solved with throttle body cleaning.
What could be the reason for this?

>floating idle speed problem
as in the rpms were floating up and down
should've had a v6

ain't a true honda without those 4 bangs man
Could possibly be your timing belt, though i doubt it since the CEL was an o2 sensor.
i looked around the internet and it seems to be an engine misfire caused by a faulty coil

Probably a cable that is leaking nerve gas.

I have the same problem on my 2l ford focus 2003
Could be the EGR valve that doesn't close
Intake Air Idle Control Valve

yeah, gonna check this one out as well, if that's not the case it could also be dirty fuel injectors
>>14686315
it would affect the idle rpm, but not the missfire

OP didn't say shit about a misfire.
Plugged up cat

op here, it looks like it is a misfire, the exhaust is "puffing" while it idles, so judging by some yt videos it seems to be the case
Does it get worse with ac/headlights/stereo on? Might be an altranator/battery/plug issue. Either that, or I bet you have a trunk sub amp with a bad ground.
>>14686411
either this or the EGR /IAC valve of course
>>14686419
nah, those are okay, ac and other electrics do not change a thing
