Pump surging - if a pump doesn't have a minimum flow it will build up discharge pressure. When this discharge pressure gets high enough the pump cannot overcome it any more and the water starts to flow backwards. When the water starts to flow backwards, the pump slows down. The impeller will start to spin backwards building up pressure again. The water inside the pump will shift back and forth wreaking havoc with your pump impeller. This cycle of spinning forwards and backwards will repeat itself and will destroy your thrust bearing and destroy your pump.
This can happen with any type of centrifugal pump, if you block the discharge the pump will build up pressure and surging can take place.

Your 2000 petrol Rodeo may be surging under load due to several potential issues, such as a clogged fuel filter, a failing fuel pump, or dirty fuel injectors, which can restrict fuel flow and affect engine performance. Additionally, problems with the ignition system, like worn spark plugs or ignition coils, could cause misfires that lead to surging. Intermittent surging can also be triggered by an air intake issue, such as a dirty mass airflow sensor. It's best to conduct a thorough diagnostic to pinpoint the exact cause.
