Misfire cylinder 3 with fule cut-off
SOURCE: 2001 bmw 325i is misfiring?
misfire happens because there is still fuel not burned in the cylinder so when its pushed out its burned in exhaust tube because the heat thats why you hear these small explosions. this caused if your sparking pluge not firing well . or there is a leak in the intake valve . in your case i advice you to check your sparking plug . if this helped pls vooote
SOURCE: misfire on cylinder 4 & 5. combustion miss with cylinder cutout.
the best way to diagnose a misfire is to move the ignition coils of those cylinders(4 and 5) to different cylinders to see if the misfire will move. you can also move the injectors around and even the spark plugs.(make sure to keep a good record of where you are moving them). if you can't get the misfires to change cylinders. your next step would be to do a compression check on all cylinders. air leaks in the intake system can cause misfires but usually it isn't on the same cylinders all the time

Replace the Oxygen sensor. All your trouble codes are downstream of the oxygen sensor, and are related to it.
Once you replace the oxygen sensor (replace with a BOSCH sensor!), remove the positive battery cable, step on your brakes for 10 seconds, then reattach the cable. This will clear the codes from your ECM (Electronic Control Module).

Spark plug wires may be the cause. for cold damp start issues water is a conducter and will send spark directly to an engine ground not through spark plugs. also look for oil in spark plug wells this can also cause a misfire under certain conditions.
