Either get higher octane fuel, or retard the timing. That is about the only thing that will help
When the fuel in an engine cylinder ignites prematurely or unevenly to cause power fluctuations and a "knocking" sound. usually occurs when an engine is very how or improperly timed.
Get it fixed.
it could be your valves or your engine
If you have knocking from the engine and smoke from the exhaust then you have far more problems than the car just not starting. Sick professional help immediately.
A loud knocking noise in the motor of a car at high speeds is most likely the engine. There could be another issue with the transmission if the knocking only happens at high speeds.
== == Upgrade your gas. Use premium grade, that will eliminate the knocking.
my car engine is on but with a loud knocking noise but when i apply some gas it does not move at all. my car is an automatic civic.
Usually when a car is making a knocking noise it is a very bad thing, which usually leads to engine failure and throwing a rod. I've had this same problem with my intrepid and was able to fix this by replacing a worn bearing on the crank. This is a deep engine job so make sure you keep track of your parts and do it safe and plan to spend 4+ hours on it.
Cant you just ask the people at the car place?
Could be a rod knock. Your bearings slipping in the engine.
knocking noise
possibly distributor. tow to mechanic . if you drive , you could damage your engine.
