Rough Idle Question
Any idea why my 430 idles rough? I'm out of warranty and want to ask on here so I don't have to drop silly money at the dealer. Thanks in advance for any help.

I had the same problem with a rough idle. It wasn't a violent shake, it was more of a minor shake or so every few seconds.
Took it to the dealer, and they lowered the idle RPM just a notch, and that helped the problem.

I had this problem on my 320
I went in complaining of a rough idle/slight shake in the car every few seconds at standstill. I got them to print the error report on the car and it said there was an issue with the front right o2 sensor. I asked my service advisor to replace the o2 sensor, but instead he recommended to reset the error and correct the values of the o2 sensor (not sure technically what they did) and my car was fine again.

Thanks for the advice guys. Ben, I took your advice and did an injector cleaning. That seems to have helped out quite a bit. ;0) I was worried it would be something expensive like a MAS; I've heard a few people saying that this was replaced to fix similar problems.
