2000"civic bogging stalling backfire on cold start ups
Need advice my civic 2000 Does not start on cold starts sometimes and Boggs out backfires even blew muffler in half . After car heats up it runs good mostly
I just changed ignition coil plugs distributor cap and rotor . Also throwing 420 code I need to know where to start looking I'm pretty sure it's an emissions proplem and not ignition . Also changed out o2 sensor upstream before the cat the b16y8 don't have one in the headers was looking for FITV to clean cant identify or does. Not have one maybe IACV EGRV I would apriciate any advice

P0420 code is catalyst below threshold, its probably o2 sensors or your cat has gone bad. Take the converter off and see if it blew apart inside.
