Hi, today under full boost between 3000 to 4500 rpm my car started
backfiring. Not a loud backfire more like the sound you here with the
stromung when you let of on the gas at low rpm and you get those low pitch
burps. It does it 2 or 3 times and then stops all the way to redline. There
is a hesitation when it does it but nothing like the violent overboost
cutout. I don't know where to start with this one. I guess I'll change the
plugs to rule out something simple. This only happens at full boost. Any
thoughts? Thanks,

Elijah
