Most likely timing is off a degree or two, fix your timing, do a tune up, and change your oil right before going, and you should be set, if it doesnt pass, then you'll need to get your cat replaced.
Another possiblity is a sticking EGR valve, holding slightly open introducing inhert gas... actually, scratch that, EGR lowers combustion temperatures, not raise them.. late night, sorry about that,
