Hello, my 95 E420 drives well most of the time but occasionally at stoplights the idle speed jumps up and down rapidly from about 350rpm to 1000rpm. It does this whether the ventilation system is on or off. It stops if I put it in neutral and tap the gas. So far the problem is intermittent but I'm worried as my car goes out of warranty soon. Thanks for anything you can come up with. Beth
