Engine hard vibration and RPM drop when letting off gas


New Member
Hey Everyone, I am looking to purchase an 2000 integra LS but the owner was reporting that his car has rough idle and when he is driving and then lets off the gas the RPM drops. So far has has changed spark plugs, spark plug wires, and valve cover gaskets.

He sent me a video and in the video you can see how the engine shakes. It sounds like some sort of misfire also? Here is the link to the video of the engine shake and sound:
