Huh? The firing order on most Honda I4's is 1-3-4-2. Nowhere do two cylinders fire at the same time.
I can't think offhand of any I4 engines that fire in pairs. Most fire one cylinder every 180 degrees of
crankshaft rotation, which is every 90 degrees of
camshaft rotation--one quarter of a full two-crank-revolution "cycle". I think you may have gotten confused by the difference between the two (which is regrettably easy to do).
