Engine clicks

My engine started making clicking noises a few days ago, and has been idling rough. I got my oil changed a few weeks ago, so that should be fine.

I made an appointment to see what’s wrong, but it isn’t for another two weeks. Should I stop driving the car until then, or is it okay to drive?

The very first thing you should do is check your oil level. Assuming the oil level is fine has sent a lot of good engines to the scrap heap. Where did you get the oil changed?

What he^ said.
What make, year and model?

I just checked the oil level, and it is fine. The oil was changed at the dealership. It’s a 2003 Ford Focus with about 130,000 miles on it. Thanks!
