Evap system will throw codes on a 96. You may have a problem with your opti if you are throwing random cylinder misfire codes and what you smell is the unburned fuel. Also, you may have a fuel injector o-ring leak. Just use a match to find the problem... JUST KIDDING!!!!!

Best thing to do is to do an Evaporative System Leak test, because there are a zillion places to look for a fuel leak. Do you have a Service Engine Soon Light on? if so pull the Code. If it is an Evaporative System Code, it will help you find the leak.

your fuel injectors are at the top of your engine and your fuel line is on the top and runs along to the very back of the engine. get a fuel pressure test done and the injectors lookes at for leaks.
