Thanks for the input, fellas!
It's just an audible thing. I haven't replaced the injector/fuel lines or the filters quite yet. I'll look at the records to see when they were last replaced. I'm pretty sure these are the stock injectors. To be more specific, it's making that sound when I accelerate at highway speeds. The popping is light but sporadic; the loudness depends on how much he engine is accelerating. Haven't taken it on the freeway, yet, but it's barely audible at a 40-50 MPH cruising speed.
I was told when I got the car by a friend to look into replacing the fuel lines and filters in the near future, and to look into new injectors. I guess now's a good time to start!
