I have a 95 Mustang and I have a problem, but i don't know whats the cause. Every time I put it in drive a part in the engine bay starts shacking, but Im not sure what it is but its coming from the top left. Also when I step on it, its kinda sluggish, didn't use to be this slow before. Any ideas?

 

When was the last time you changed your plugs? Or wires? Maybe one loose or burned and grounding. Air filter too. Clogged and choking. I know it seems basic but you would be surprised how many people think it has to be something major when in reality it can be simple. Usually the smarter the person, the worse the problem is. Computer geeks can't go into a computer and open a file. They have to go to DOS, re-route the world and then backdoor something when all you have to do is simply hit "enter". Same with some "expert" car mechanics. Always a rod, crank, something deep to find out later it was a loose wire. Good luck!
