As a rule of thumb, fuel problems come on slower and last longer on the intermittent side. Ignition problems are more likely at fault. They can come and go in a single revolution where a fuel problem would usually last several revolutions. Since it is intermittent, and being a '99, it may have recorded the misfire in a code. The PCM records every misfire in its diagnostic data. A good scan tool can get in and see how many misfires have been recorded on each cylinder. Checking the plugs can also offer a clue. If one id differently colored than the others, it would point to a problem with that cylinder. BTW, yours should have a DIS coil pack and not a distributor. One thing to keep in mind about scan tools and diagnostic info: Every fault that the PCM detects is recorded. A high or low signal from a sensor, a random misfire, etc. This info does NOT necessarily set a code until it becomes frequent enough to trigger a code. Faults that fall under that threshold are stored as diagnostic info. In most cases, faults are stored first as diagnostic data, then as pending codes, then finally as trouble codes that light up the "check engine" light.
