My car seems like it runs real rich like you can still smell the gas from the exhaust. Is there a way to adjust the fuel lean and rich??

thats controlled by the ECU. If you still have the stock ECU, try a new oxygen sensor

That would probably explain the check engine light going on and off too huh? How much is a new O2 sensor? are they hard to install?
