Car making a nocking sound and cutting off - 1996 Dodge Intrepid

Make, model, engine year????

Whoa. Stop. Take the valve cover off. You'll probably see the problem. Maybe a rocker arm has come loose.

Lifters generally make a tick, tick, tick noise. If you have a low tone knock, you may have more severe issues, or what you may have is heavy carbon build-up on the pistons, contacting the cylinder head(s). What I suggest first is to use fuel injection cleaner and add it to the fuel tank a few times. You can go to your local part store and see what other products they have, such as "Seafoam," to assist in carbon removal. Extreme conditions may actually require the removal of the cylinder head(s) to gain access to the top of the pistons to physically scrape the carbon from them.

There is nothing to be done except replace the engine.

Try it with the serpentine belt off,could be the damper,could be also the bolts that hold the torque converter to the flywheel,just pulling a plastic cover will access the bolts.

sounds like the flex plate ,this holds the torque converter to the crankshaft

Sounds like a bad cv joint. Replace the axle on the side making the noise.

It sounds like you may have some sludge in your oil. When the engine is cold the oil is thicker and takes a while for the oil pump to pump it through the engine. The next time you change the oil. Do an engine oil flush first to clean the inside of the engine and ports. If this does not work you might have to have the oil pump checked. There is no need to worry as long as you have oil pressure and the knocking stops. I hope this helps. Don't forget to rate this answer.

sounds like the gearbox to me

I had a similar sounding problem with my car (Renault Clio), it could be that the drive shaft is gone. You'll need to bring it to a mechanic to get it replaced unless you can do it yourself.
