Hi, my name is\*\*\*\*\* to justanswer. I will be assisting you with your question today. I am sorry that you are having difficulties with your vehicle and will do my best to help you out. Have you had the opportunity to do any visual checks around the engine? Checked oil level, anti freeze, etc? Does this knocking noise speed up and slow down with throttle response? **\*\*As far as phone calls, If you didn't request it, it is most likely the Website prompting you, not me. A Live Call is a "Premium Service" and will cost more money. I prefer communicating via this site, but in some cases a phone call may be recommended\*\***

the knocking does speed up \*ü\*JessicaüNüChrisüNüKids\*ü\*it does speed up and slow down with the throttle response

Have you had a chance to check for codes?

What is that \*ü\*JessicaüNüChrisüNüKids\*ü\*
Automotive Expert
You said the check engine light came on. An electronic scanner would be used to retrieve codes from the vehicles computer to help diagnose the problem.

No I haven't done that \*ü\*JessicaüNüChrisüNüKids\*ü\*
Automotive Expert
I would also check and see how much motor oil is in the engine. To me it sounds like the motor had an internal failure and is not operable.

will I have to replace the whole motor \*ü\*JessicaüNüChrisüNüKids\*ü\*
Automotive Expert
If it is something like crankshaft bearing failure or piston and connecting rod failure, yes, it would usually require an engine replacement.

alright thank u
