I've noticed that my Ford Focus has been idling very roughly lately. What could be causing this and what steps can I take to fix it?
ReplyA rough idle in a Ford Focus could be caused by a variety of issues, such as a dirty air filter, a faulty fuel injector, or a vacuum leak. I recommend checking these components first and replacing or cleaning them if necessary.
Another common cause of rough idle is a problem with the spark plugs or ignition coils. I suggest checking the condition of these parts and replacing them if they are worn or damaged.
