That may be best left to an independent repair shop. Short of performing maintenance that may be due or overdue, you need to know what the data stream is doing when the problem is happening.
The least likely cause of an engine hunting and surging at top no-load speeds is a malfunctioning fuel injector. Other factors such as an incorrect fuel-air mixture, vacuum leaks, or issues with the ignition system are more commonly associated with such symptoms. Fuel injectors typically affect engine performance under load, rather than at no-load conditions. Therefore, while they can influence overall engine behavior, they are less likely to be the primary cause of hunting and surging when the engine is not under load.
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.
depending on load and accesories,or if it has air!! check at a auto parts store or dealer.
It sounds like the alternator or regulator is breaking down under a load while driving. Make sure the alternator belt is tight, and check the regulator and alternator for proper voltage under a load.
When a compressor experiences surging, it is essential to immediately reduce the load or throttle the flow to stabilize the operation. Inspect the system for issues such as improper control settings, inadequate suction pressure, or blocked filters. Additionally, check for mechanical problems like worn bearings or misalignment. If the surging persists, consult the manufacturer's guidelines or a qualified technician for further diagnosis and corrective measures.
When under a load the errors will be shown faster
Increased Engine load = more amperage
If only under load then......spark plug leads.
sounds like a cranksenser.it will put your timing out when your under load .markstang
Surging in a chiller system is typically caused by fluctuations in the refrigerant flow or load demands, leading to an imbalance between evaporation and condensation rates. This can occur due to issues like improper system sizing, blocked refrigerant lines, or malfunctioning expansion valves. Additionally, changes in ambient temperature or pressure can exacerbate these imbalances, resulting in inefficient operation and potential damage to the system. Regular maintenance and monitoring can help prevent surging by ensuring optimal system performance.
