When I start my 2000 Grand Caravan, it makes a loud knocking sound and when I accelerate, it rattles, I can feel it behind the accelerator pedal. It has only been doing it a couple of days now. We changed the oil, and it is worse now than before the oil change.
Hi is it miss-firing as it sounds like a knocking noise can be anything but if you can feel it on the accelerater pedal then the noise sounds like its on the inlet valve side which would transfere the noise up the throttle body where the accelerater is located it could be something as simple as a tappet come loose to a burned valve you need to have a look do a compression test and take the rocker cover off see if theres anything come loose yates210456
Sounds like lack of oil pressure or rubber mounts Are you still driving it?Maybe check Engine mounts
