Greeting everybody. I had my ride out yesterday and my 427 began to backfire out of the right side bank. I pulled over and took a look under the hood, checked the spark plug wires and couldn't find any obvious problem. I started it back up and it ran fine for about fifteen minutes and again it began backfiring from the right side bank. Stop again, checked everything, started it back up and took it home without any more backfiring. Where would you suggest I start looking? Sticky valve, bad plug?
