I have a 97 Lumina that will sputter and shake an lurch when it gets up in between 45-65 mph. If I step on the gas, it works through, until I get back to the normal speed limit, or stuck behind someone doing 50, it will start up again. I keep on accelerating to get it to stop, but then have to slow down so I don't rear end someone. Please help.
