I have the same problem with my 560SEL!! It has been shaking like crazy lately and I've replaced my OVP relay thinking that would help (although the fuse was still in good shape,I figured that maybe the relay itself was bad and replaced it anyway-glad I didn't toss my old one because its probably still good).She always starts right up though,and has never stalled.I just came back from lunch and noticed that pulling off from a light that as I push the accelerator, she shakes and even though I'm barely moving, its using a ton of gas! I'm thinking of changing my spark plugs right after work to see if that helps.I hope that's what's up although its probably more... any ideas here? Secondary ignition components?
