answer:Dear I really think it’s time you buy a new car, lol. Anyways, this could be a lot of things. My immediate concerns are either your engine is knocking, or your motor mounts are going bad. If the engine is knocking, this means it doesn’t have enough oil. The “knocking” sound is the pistons hitting on the metal everytime they go up and down. It would probably be getting worse (louder and more frequent) when you were accelerating though. So the good news is it’s probably not that. Either way though it never hurts to check your oil (especially with your car). Keep an eye out for any shiny objects in it if you can (those are metal shards). If your motor mounts are going out, you would notice the car kind of “pulling” itself from the ground on one side (not both). The motor mounts literally mount the motor to the frame of the car, when they are going bad they start allowing the engine to twist as it’s momentum would like it to do. This also though would present itself more powerfully while accelerating (in my experience at least). If you want that checked you’ll probably have to ask someone knowledgeable on cars to check it for you. The only other kind of major concern is one of the belts (which thinking about it is probably the most likely culprit). A belt could be slipping or knocking when the car is colder (aka if it goes away after you’ve been driving this is a good symptom of a belt). Easiest way to check is to turn the car on and pop the hood, look/listen for noises or what have you. Honestly without more symptoms or information it’s kind of hard to tell, but there’s some things to start worrying about, lol. But like I said… new car time… lol
