Re: 454 engine backfiring by John Ogletree
Post New Message When I had this problem on my 454 it was caused by alternator failure. Must have happened as I was driving and I didn't notice it until the battery was so low it could not fire the spark plugs consistently, so unburned fuel started exploding in the exhaust system. New battery and alternator fixed it.
