After living thru "dancing dash lites" and WS wiper problems now my '92 500SL has developed a couple more electrical annoyances. My ASR light comes on intermittently and also the engine has suddenly begun to idle quite rough- this is also intermittent, most of the time it idles just fine and at speed I notice no roughness in engine running or deterioraton in performance. Has any one else experienced these problems and hopefully found a fix?
