the entire car yesterday started rumbuling and shaking when i drive it. when at a stand still the entire car is shaking and when i drive it stalls and cant really go past 40mph. it was running fine and all the sudden i start it up yesterday and this happens i have no idea what this could be. the check engine light is on and the battery light is on. the battery light has been on for about a week and a half now and ive replaced the alternator and the battery and starter were both good 5days ago when i chaked them so i honestly sont have the slightest clue of what this could be.
