SOURCE: Fuel leak (smell is in the passenger vent) but cannot be located.

sounds like it could be a leaking fuel rail. you should fix this very soon. if it is it is a fire hazard. that is if it is under hood and not underneath. look under vehicle and check for wet spots.

I have a 2002 buick lesabre gas smell inside the car they said its the map sensor


Ok, Is there a question?
Usually with gas smell, I look for external gas leak? If I find nothing, I check the evap system. Next, I check if the vehicle is running rich or lean? Were there any applicable trouble codes? If so, what were the codes? The map sensor could have a problem?

What kind of Spark Plugs did you put in? If your answer is BOSCH Platinum? THROW THEM AWAY.

My 2001 buick lesabre is pulling a random misfire code and spits and sputters and smells like the car is floading


find the fuel pressure regulator. you should see it mounted on the return line of the fuel rail under the plastic engine cover. it will have a small vacuum hose attached to it. Remove the hose and see if gas comes out of the regulator. If it does replace it immediately.
