Hi everyone. I am still trying to find out what is wrong with my 325i. When you are sitting at an idle it idles real rough and the interior and exterior lights dim and then get brighter over and over again. I did a ignition tune up and alt test and it still does it. I have a friend that sayes a burnt valve can cause this. Is that true?
