Check Engine Light?

[1htcivc]

so my check engine light came on yesterday in my EK SOHC civic.. the only thing i'm noticing is that when i'm sitting still it idles kinda rough.. anybody ran into this before and know what's wrong??

Really not sure, check your vacuum hoses.. fuel pump/filter... pcv... grounds... could really be anything.. you should get the code by shorting out the plug by the ecu.. watch for the cel flashes.. count em.. then look up what the ecu is reporting.

What year is your car? If it's OBD2a/b... check your gas cap.

disconnect your battery and then reconnect, this will reset the codes, something could have and just sparked the check light. if it comes back on then something is wrong.

DO NOT DO THIS, until AFTER you figure out what code it threw, there's a reason why the CEL went off, dont just reset it.

go to autozone and have them check it for you. its free.
