Each time I press the acceleration pedal I hear a knocking sound, but my engine is sound and there is good oil in the engine. Someone said it's a plug, that I should change my plugs. So, I'm confused.

I am not sure this would be caused by a spark plug unless you have a misfire.

What I would suggest we do is start with you getting a video recording of noise so that we can get on the same page with you.

Basically, if we make an assumption on this it could be way off. So, this could be a misfire or even an engine knock, so we need to start with getting on the same page.

Also, we should check and make sure there are no codes as that would cut down on a lot of checking.

If this is a misfire, here is a guide that will get us started:

Basically, we need to run through this info and let us know what you find.

Thanks
