Yesterday a strange noise started coming from my engine. After driving around 30 or 40 miles (no noise) and going on some dusty roads (I don't think this would matter) I started the car up and the engine sounded rougher and less smooth. Its difficult to describe, but its not a clicking or anything like that, the engine just sounds rough. It drives normally (I've been driving very conservatively), I check all fluids and engine oil was a half quart low (don't think it matters, it's been 2,000 since the last change and it is usually down that much by now). I'm curious (and worried) as to whats going on. I'm calling my mechanic first thing tomorrow morning, but any ideas?
Thank you in advance!
