upload this video, this is what it's doing. Also when trying to accelerate the car doesn't accelerate correctly, until it hit a certain point.

Have you checked/ replaced plugs?

 

Is that rod knock I hear?

 

Any CEL codes? How's your oil right now? Check timing?

 

that **** does sound like rod knock. sounds like a freakn diesel engine. well anyways since it happens when you let go of the gas ill say check your throttle body plate make sure it has no black soot around it if so as the vacuum pulls it shut the black soot covers the lil gap its suppose to have to keep it breathing. or it could be a open egr. and that stumble upod accelerate i would say it is egr, but if you pull the spark plugs out it will tell you whats going on with the engine

 

I drain out a lot of my oil, and still it's still up on the second dot. I don't know what happen my brother change my oil. I don't know what he did to it, but I sure did drain a lot out.

 

egr? I don't see it on my car I also google it and they say that it doesn't have it on my year EX. yeah I'm taking the tb off and cleaning it. what do you mean pull the spark plugs? you mean while the car is running? or??

 

More than likely it's plugs if it stumbles during acceleration. Could be vacuum leak or bad intake manifold gasket or tb gasket. What about valves I had slight miss in gsr and it was due to bad valve. Could be a number of things but I would start with the easy stuff. Any codes?

 

I was having a similar problem. I'd check timing for sure. Do a compression test and let us know the results. Got any blue smoke coming out the exhaust?

 

Sounds like poor compression or the timing is off

Low idle - Clean the IACV and adjust the idle speed.
