Why does my BMW M8 have a lumpy idle?

I recently purchased a BMW M8 and noticed that the idle is quite lumpy. It's not smooth and steady like it should be. What could be causing this issue?

Hi James, a lumpy idle can be caused by a few different things. It could be a problem with your spark plugs, fuel injectors, or even a dirty air filter. I recommend taking your car to a mechanic to have it checked out.

Hey James, the lumpy idle could also be due to a vacuum leak. Check all of your hoses and connections for any cracks or leaks. If you find any, replace them and see if that solves the issue.

Hi James, another common cause of a lumpy idle is a faulty oxygen sensor. This can affect your car's fuel mixture and cause a rough idle. Have a mechanic run a diagnostic test to see if this is the issue.
