Smell of Gas
it sounds more like u have leaking injectors. You should unscrew the fuel rail and lift the injectors/rail out the turn the key on and see if any leak..Make sure u use plenty of rags and/or a bucket.
highly doubt a fuel issue has anything to do with an opti...leaking injectors is my call...how many miles are on the motor?
there is a little oring that goes around the injector and it can blow, therefore causing the injector to leak...

u could try thread sealer or a thread chasing tap....anyway like was said before focus on why u created this thread in the first place and use the suggestions that was given to then move on to the next problem !
after hours of reading, im now wondering if i put the crank pulley on wrong? is this possible? if so anyone have a picture of what it looks like correctly installed? i just saw on a webpage somewhere someone was having the same problem as me and it was his pulley installed wrong causing him to have the 6000+ RPM misfiring
