MisFire?
Today my cel turn on. I ran to nearest auto shop and see what going on, and i got all those code from ecu code scanner P0301/ 1 cylinder misfire, P0302 C 2 misfire, P0303 C 3 misfire, P0304 C 4 misfire and P0300 random cylinder misfire. Total of 10 codes, what cause all those problem? It seem to drive fine. 
there could be multiple things, most likely in your ignition. im assuming your having this shop work on your car so just ask them what they think was the cause, if they arent sure then take it to someone else or honda.
whats your mods, could be low fuel pressure, compression, VTEC malfunction. Do you notice when it misfires? What other codes are you getting? P0107, P0108, P1128 P1129 (MAP sensor) Let me know the other codes besides the cylinder misfire ones.

Rep Power: 0 i'm running cai/hp head with test pipe/apexi n1 exhaust/ v-afc2 that all i been running those mod for year and half untill today my cel come on. that the only codes i get is misfire. My car been acting up funny latey like with i start my car it rev up and down untill my car warm up.
my bros audi misfired in one cylinder, you would only feel the car "putting" (i suppose you could call it this) when the air was damp or raining out. sometimes youd be accelerating and feel it just like give up and the car would stutter pretty much. he just needed a coil pack replaced but i doubt you need all 4 so just take it to honda cus even if you figure out what it could be online here youd be better off jus havin them do it.

Rep Power: 0 When i start my car cold early in morning or leave my car outside for couple hrs. When my car is idling around 2k(cold start), if i open my glove box my rpm bounce down around 1k and go back up to 2k. It keep on doing that when i close and open my glovebox. When my car is getting warmer my rpm dropped, if i open the glovebox nothing happen my rpm don't bounce. It could be my ecu because my ecu is next to glovebox or it could be my faulty wires from afc but i have my afc for almost a year?
