2012 50i Repeated Cylinder 2 Misfire

[friendlystart]

I have been repeatedly having the cylinder 2 misfire and recently replaced ignition coils and plugs. Also since I have 117,000 miles on my 2012 50i I replaced all four Vanos solenoid valves and both O2 sensors before the Cat because of rough startup idle and fault codes. However I still get the fault engine code for cylinder 2 misfire. Even cleaned the MAF sensors. Any ideas to what may be causing the repeated cylinder 2 misfire would be greatly appreciated!

Thanks

Most likely your injector, replace them all if you have the $$$ as the rest are sure to follow. Either way order the index 12 injectors. FCPEuro has excellent prices on them
