Could be a slight timing issue, but I wouldn't worry about it. Just minor backfiring through the exhaust, so unless it sounds like its going to blow your muffler apart just turn up the stereo...
Having said that, a tuneup is always a good idea if it hasn't been done recently. Cap, rotor, spark plugs (NGK, not Denso), and maybe new wires if the old ones are cracked. That's not the complete list, but a good start on it. Oh yeah, and set your timing too!
