Random Backfire

Every once and awhile I will be driving around town and my truck will backfire. It has happened about three times in the last year. Dealer found nothing. Anything I should look for?

Potatoes in your exhaust pipe.

Horsey's cock and balls in your exhaust?

I honestly have no idea. My truck did it once when I first got it and never again.

Backfiring is an ignition timing issue. Could be the ignition amplifier module. Does it happen in wet conditions?

Well that does bring up the fact that I want to replace my exhaust. Tail pipe has a small crack. I really want to replace it with something that doesn't sound too obnoxious but also looks a bit better than stock. I doubt it is causing my issue though.

check the air hose from the plenum chamber to air filter box ... if the air reaching the engine doesn't match the sensor readings then backfires are possible ...

Thanks Jason

There is a crack in the air hose from the plenum chamber to air filter box. I am putting together a RN order now.

Time to start doing some of this stuff myself.
