The knocking noise is commonly called spark knock. The knock can be called by the engine timing not being set correctly, or using gas that has too low of an octane for the engine.
A knocking noise can occur from worn engine mounts. When the rubber insert on the engine mounts are old and brittle the chassis is not protected from the weight of the engine. Creating loud vibrations that get louder as the vehicle goes faster.
knock sensor is going bad or is bad
a "knocking" noise could be your lifters. and the ticking when accelerating and letting out of the gas is the same thing. check your oil and if it's full then you may need to think about either having them adjusted, or getting new ones. depending on what you have depends on whether or not you wanna sell it
knocking noise
By replacing the chain and tensioners.
Most likely needs a tuneup done. Check the timing and change the normal tuneup part.
NO. A knocking noise in the engine is a problem in the engine.
I get knocking & ping noise coming from the fuel injectors
A bad harmonic balancer can cause a knocking noise. The harmonic balancer doesn't actually produce the noise, but it can cause the noise in the engine.
Usually a "knocking" or "ticking" noise when under acceleration means cheap fuel grade. Next time go for the gas with more octane such as supreme.
A clicking noise, when accelerating, can be caused by a worn CV joint. The CV joint can cause the axle to collapse when it breaks.
When your engine has a knocking noise, it could mean that a rod has been thrown. It could also mean you are low on oil.
