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

You have to ask the dealer to look up your code for you. Then you have to leave the key in the first position (do not start car) and leave it for 1.5 hours. Then come back and radio will accept your 4-digit code.

I only have a couple suggestions. Double, double,double check the ignition wires. More often than not, they will be place in the wrong firing order. If have done that and problem persist, replace all the ignition wires withnew, and double check the wiring order. I'd be interested to know if this is the same symptoms it had prior to you replacing the plugs or after? Good luck
