Smelling gas fumes inside car
You're Oldsmobile has an emission control device called EVAP. What it does is allows gasoline fumes to be sucked into the engine and burned instead of being released into the air. There are fuel vapor lines going from the gas tank to a charcoal canister, under the hood, then from the charcoal canister to the engine. I'm assuming that you aren't seeing any gas leaking so check these fuel vapor lines for damage and proper routing. Also be sure you're using the correct, non-vented type of gas cap. HTH. -Jim
