- Low oil pressure: When your engine is hot, the oil thins out and loses its ability to lubricate the moving parts in your engine. This lack of lubrication can cause the engine components to move slowly or even seize up completely.
- Insufficient coolant: If there isn't enough coolant in your engine, it can't properly cool the engine and this in turn can cause the engine to run hot and slow down.
- Faulty spark plugs or ignition components: When the spark plugs or ignition components malfunction, they can lead to a lack of sufficient spark to ignite the fuel, causing the engine's revolutions per minute (RPM) to drop.
- Mechanical issues: Serious underlying issues, such as wear of engine components and cylinder compression issues, can cause your Ford engine to perform slowly when hot.
If you're experiencing this issue, it's important to take your car to a mechanic for diagnosis and repair as soon as possible to prevent further damage to the engine.
