my 99 Honda accord ex 3.0 I have a question on the firing order oreillys computer told me that was 123456 and the distributer says its 142536 now which one is right cause I did it both ways and it starts everytime on 123456 but runs very rough and it don't start everytime on 142536 but runs better but at higher rpms. thanks ahead of time.

 

 

thanks for the info, I have replaced the map sensor the iacv and the tp sensor and it is idling high now why would it do that it didn't before.
