Knocking sound in engine when accelerating on passenger side. Cannot figure out what the problem could be. Would like any help that I can get with this problem. Other than the knocking it runs very well.
Do you
have the same problem?

Hello my name is Dave.

Can you get it to make the same noise when it's not moving? Our first step needs to be narrowing down the source of the noise. Do you feel any kind of vibration when you hear the noise and do you have a check engine light on? If it is an engine noise it should trigger a code for the knock sensor and it should also loose power due to the computer retarding the timing in an attempt to stop the spark knock, even though it is obviously not a spark knock the computer can not tell what the noise is just that it is present. If you can't reproduce the noise while not moving and don't have a check engine light I suspect your noise may not be coming from the engine.

If you can reproduce the noise while the car is not in motion then I would suggest getting a mechanics stethoscope and pinpointing the location of the noise, you can get a stethoscope at Harbor Freight for $4.99.

If you don't have a Harbor Freight where you live you can also buy one on Amazon for less than $9.00.

If you could let us know if the noise is only in motion and what the exact conditions for it are, such as car speed, going up hill, or if it does it sitting still what the engine speed is when it happens we will be glad to guide you further to narrow down the problem

Please keep us up to date on your progress and thank you for using 2CarPros!
