I'm trying to track down a misfire, and it unfortunately wasn't the obvious stuff like plugs or wires. I'm trying to figure out why the misfire is occurring (to much fuel, not enough fuel, not a consistent spark, etc). That will help me know which system to look at more carefully.
Because it's a somewhat old car (17 years), I'm suspecting the fuel filter may be causing issues. If that were the case, I would expect a lean misfire. Would a lean misfire give off the smell of unburnt fuel?
