hi everyone on my 2009 328xi i am trying to diagnose my issues with no luck. My symptoms are a rough idle on start with the rpms being anywhere from 500-900, it drives just fine. I have P00BC, P0302, P0301, P0300, P0303. i recently bought this car and the last owner had a cold air intake that i thought was making it throw those codes. after replacing it with the stock airbox and replacing that MAF i am still getting the same issues. I have ruled out a vaccum leak, the ignition coils, and plugs. has anyone else ran into the same problem and what helped them. I am pretty sure all the other codes are being caused by this MAF code. Thanks in advance
