Most engines require a minimum amount of oil pressure to function properly. If the oil pressure is too low, it can cause a number of problems, including a rough idle.
Low oil pressure can be caused by a number of things, including a clogged oil filter, leaking oil seals, or a damaged oil pump. If you suspect that your oil pressure is too low, it's important to have it checked by a mechanic as soon as possible.
If low oil pressure is the cause of your rough idle, it's likely that your engine will also make a lot of noise. You may also notice that your engine is running hotter than usual.
If you're experiencing a rough idle, it's important to check your oil level and pressure as soon as possible. Ignoring the problem could lead to serious engine damage.
