Ground out the service connector in the passenger's footwell to be certain (half a paperclip works). It'll blink longs and shorts, which, respectively, represent tens and ones place digits, thus giving a specific numeric code for the problem.

when you drive, does it boggle from 0-3000 rpm's especially on first gear? I had that problem once, car boggle but after 3000 it ran fine. Check engine light came on, didn't know what to do and took it to honda for a diagnostic test. They said my o2 sensor was bad, swap it out and runs excellent now.
