Newb Here! 07 NBS silverado, Ive got a miss on number 2 (p302 code). What Ive done so far: changed the plugs, wires, all the coils, checked all the injectors they have a strong pulse, cleaned MAF sensor. I really don't know where else to go from here cause now the 'stabilitrak needs to be serviced' light comes on to. The dealer told me if I fix the 'miss' it will probably correct the stabilitrak error (sense the tcm and pcm work together he said). If I disconnect the battery and reset the computer the check engine light goes off and I may not see it come on again for another month. Then out of the blue it just comes on again. Question is, could my computer be going bad? Would an O2 sensor cause the miss? Really don't think theres any vacuum leaks.
