I replaced my battery on my 560 SL with a non-mercedes battery and ever since, the idle has been a little less smooth. Does the battery have anything to do with the way the car idles or performs once its running?
Well it shouldn't, unless it wasn't as big as the previous one. The battery should 'soak up' the charge coming from the alternator, and sort of 'even it out'.
When you say less smooth, what do you mean?
