I've got a 2004, 2.4 Petrol, Manual Accord and the engine management light is on. I've been told that the Cat's listed as the problem but, I can't find the exact cat that I need. Will it be the same cat used on the Manual and the Automatic? Is it just a cat from a 2.4 that will fit? And, is it me or are Honda part numbers and specs really hard to come by...?
