I get knocking & ping noise coming from the fuel injectors

Knocking when you step on the gas can be caused by several factors, including engine knocking (pinging) due to improper fuel octane, which leads to premature combustion. It may also result from worn or damaged engine components, such as bearings or pistons, that create excessive clearances. Additionally, issues with the fuel system, such as clogged injectors or a failing fuel pump, can lead to inconsistent fuel delivery, causing knocking sounds. Regular maintenance and using the correct fuel type can help mitigate these issues.
Try a higher octane fuel

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.
they are the same thing. "knocking" in an engine is the fuel igniting from the heat of compression of the fuel and the air together. in a desel engine this is how it is suposed to work because it has no spark plugs so the only way to ingite the fuel is by compressing the fuel and the air by a ratio of about 22 to 1. in a gas engine the fuel is ignitied by a spark plug, if you use low grade fuel the explosion can happen too early (before the spark plug ignites it) and cause a knocking noise in the engine whitch can cause dammage long tearm the typical compression ratio for a gas engine is 10 to 1. the more compression you have the higher grade fuel you need to prevent "knocking" whitch is why higher end cars need higher grade fuel because they have higher compression engines whitch make more horsepower with omperable size engines.
change fuel pump
Adjust timing and/or quality of fuel
Bad fuel pump, loose fuel pump, loose baffle or foreign matter in the tank.

The knocking problem is less prevalent in diesel engines primarily due to their higher compression ratios and the nature of diesel fuel. Diesel engines operate on the principle of compression ignition, where fuel ignites from the heat generated by high compression, rather than from a spark. This results in a more controlled combustion process, reducing the likelihood of pre-ignition or knocking. Additionally, diesel fuel has a higher cetane number, which contributes to smoother combustion and further minimizes knocking tendencies.
