Hey everyone i was driving home getting off the freeway when all of a sudden my car starts to smell like rotten eggs. I know its the cat that was going bad but then my check engine light started flashing and my car ran like crap. I made it home and shut off the car right away. I turned the ignition like if i was going to start the car and i had no cel. The car is a 2000 honda civic ex its all stock besides dc headers its my daily driver so it has about 150xxx. Could it be just the cat or is it something worse please help

 

flashing cel= missfire, the rotten egg smell is raw fuel burning in the cat. need to find why it is misfiring.

 

on that diag. rotten eggs isnt a bad cat. pull your codes and fix it ;-)


lets not go replacing good ***** cats

 

alright well the car was sitting for about 2 weeks and ive been driving it for 4 days already and the car was driving fine before.. well imma pull my spark plugs and see what they look like
