So my 2010 Ford Fusion will shake when i am at a stop but as soon as i give it gas it will be fine. Only happens when it is in drive or Reverse and i have the brake pressed down. I have changed the Spark plugs, Valve cover gasket, Belt drive and pulleys and nothing it still shakes. Could someone help please it shakes the steering wheel and interior. It doesn't shake while stopping it only shakes when at a complete stop.
Also The car makes a weird rattle noise when i accelerate too hard usually at about 1800- 2300 RPM but only in first and third gear.
Please help.
