What's up guys I'm having a little issue I own a 3.8 cylinder 01 mustang all stock ihad an incident a couple days ago . After a regular hand wash car wash the car would start it wasn't the batter but after a couple mins of waiting it started . 1 day later the engine started shaking a little and moves the whole car whenever it's in park or at a stop ? Any idea what can be going on thanks in advance for the help !
