It sounds like detonation. This occurs when the air/fuel mixture ignites in the cylinder before it should. I can be caused by incorrect timing or even red-hot carbon deposits in the combusion chamber. I would tend to belived the 2nd suggestion as cars tend to run hotter in traffic.

Try running some Marvel Mystery oil in the gas. Use the recommended dilution on the bottle. If that doesn't work, GM top engine cleaner. It can be purchased at GM dealerships. Follow the directions on the can.

Lost of power, knocking sound


HAVE YOU CHECK YOUR OIL LEVEL? OR OVERHEATED THE ENGINE, CHECK THE ENIGINES OIL LEVEL, YOU MUST OF LOST OIL, RAN LOW ON OIL OR YOUR OIL PUMP GAVE OUT. IF THERES KNOCKING OIL NOISE, THATS NOT GOOD AT ALL. ASLO WHERES THE KNOCKING FROM TOP OT THE BOTTOM. THE TOP IS LESS TUMPING THE BOTTOM IS HARDER TUMPING AND SOUNDS HARDER WHEN ACCELARATED. LET ME KNOW. CHECK THE OILS CONDIOTION FOR GLIDERIN THE SUN YOU SEE THE RESEDUE METAL GLIDERING. IF SO THE MOTOR IS MOST LIKELY SHOT.

Chain rattling noise


Locate the knock sensor on your engine. Quick test on them is to tap on the engine with a small hammer near (not on) the sensor. If engine rpms do not change then likely the sensor is bad. Likely what you are hearing (if it is coming from the engine) is detonation. If the noise is elsewhere, it could be a bad chain in the transfer case, but that would need to be looked at to evaluate the problem further.
