Do you know what the number is? If you ground A/B and (after the 1,2 - 1,2 - 1,2) you get 4,4 - 4,4 - 4,4 - that code 44 means lean reading from O2 sensor) - if that's the case, it's either b/c (1) you're lean at WOT (need to boost fuel pressure; maybe fuel pump is going out -0-->major bummer!) or (2) your O2 sensor is shot/not making good electrical contact...
(just a guess)
