Q: Fuel rich smell from car

asked by on

I detect a fuel rich smell when I start my car and for a little while afterwards.

A: I’m not sure if you mean you smell fuel or ...

I’m not sure if you mean you smell fuel or your vehicle smells like it’s running rich. If it’s the latter, there are dozens of reason for a rich mixture.

I suggest having a trained professional, such as one from YourMechanic, inspect your vehicle’s smell to see what repairs can be done.
