Rough Idle

So I have an 03' 330i that has roughly 140,000 miles on it. For about 4 months now, I've been experiencing rough idle at cold startup. The RPM ranges between 500 and 2500 and occasionally stalls when I come to a stop. The codes I've gotten are:

2882
2883
27dA
2783
278C

I've been reading a lot about this lately and have been thinking about doing the following:

Clean both the ICV and throttle body
Clean MAF sensor

I haven't gotten a code for any leaks so I doubt I have a leak anywhere in my intake.
After I do those two things, do you guys suggest I try anything else before dumping more money into the car? Any help is appreciated. Thanks

What tool are you using to gather codes??

Best to use a standard OBDII tool and post Pxxxx codes and Freeze Frame info.

OBDFusion is a great, low cost App that does what you need.

Throw the Peake Reader piece of crap in the garbage.

How about you properly translate the codes and post the definitions? Do you expect everyone here to look all of this up AND offer help? And do you REALLY know the difference between a 6 and b?

OBDFusion and the proper VeePeak interface is under $30 and will RUN CIRCLES around the Peake Reader.

Android App $3.99, VeePeak Bluetooth interface on Amazon $13 for a total of $17!
iProduct App $9.99, VeePeak Wifi interface on Amazon $17 for a total of $27!

You get codes in the PXXXX format, Live/Realtime and Freeze Frame Data, Logging capability and Diagnostic Reports. This along with seamless DropBox integration and it works in any 1996 and newer North American market passenger car and light truck. It is the Driveability tool to have.
