My Ride: 05 jet black 545i ya...
after doing some searching in these forums, I feel that I need to change my spark plugs due to my rough idle issue. The MAF is less than a year old and I also had the valve cover breathers? replaced since the dealer said they were torn. Does this seem like a logical repair for me to replace the spark plugs? Also do I need to replace the coil packs? I am NOT getting any misfire codes, however, ever once in a while Ill get an iDrive engine malfunction warning.

I would definitely change your spark plugs, especially if you're still running on the originals.
I just did the 60,000 mile service on my E60 last weekend (2008 550i), including new plugs. My car was running fine, and the engine is in tip-top shape (had the oil analyzed at Blackstone and got a glowing report), but boy howdy I can tell you that I noticed an immediate change in how my engine runs with new plugs! It idles much smoother, and takes off like new car again. I had been developing a bit of a hesitation from a dead-stop (which nearly caused an accident a couple weeks ago when I floored it to get into traffic and the engine just about quit!), but that annoyance is definitevly gone now. My car runs like she's fresh from the factory again.
It's a cheap fix with a nice bang-for-buck return.

OK, i also want to add this and see if anyone has any thoughts. When sitting at a light lets say, rpms will bounce around up and down about 200 rpms, and i notice the car vibrates a bit, then every once in a while itll will be a violent shake and the car almost wants to surge forward...its really strange. anyone have an idea? or happen to them also? Alternator?

Not on my E60, but I've had that problem with my toyota before. Engine light on, rough idle, and at times the entire car shaked. Dealership diagnosed as one of the coil pack was bad. Subsequent to the replacement, had no issues. Hope this helps.

Any change to your car idle behaviour 545iNTENSITY?
I am experiencing the same thing and also think it's the plugs and coils. I will get them changed next week.
Thanks
