Hello everyone.
It seems like I have an issue.
Can you please watch the video and tell me what is the problem.
Thank You.

 

Assuming it's a 93, check for codes.

Initially, my thoughts are it's not good. What RPM was the engine at? Seems high.

 

Flat cam or lifter bleeding down allowing the valve not to close properlt

 

Sounds like she's missing. Check you plugs, plug wires, and Optispark. Also check for a leaking fuel injector.

I had a 95 Impala that sounded like that after sitting for a bit. It wound up be rust that had built up on the valves. I just cracked the throttle for a bit and the engine knocked everything loose and ran fine afterwards.
