Backfires in the manifold. Replaced spark plugs, wires, coil pack, coil pack, plate MAP sensor and O2 sensor "Upstream", air intake temperature sensor and the air filter. Still have the same problem and code is still there. It does have a bad muffler and a small hole in the exhaust. Please help. Thanks in advance

What is the code that is set?
