Misfire after filling the fuel tank and p0172 diagonous code

Answer 1

HI there,

The most common cause for the misfire after fueling is a sticky purge control solenoid valve. This is stuck open allowing the gas vapors into the intake while you fill the car with gas. The result is a flooded engine which in turn will cause the P0172 rich fuel mixture code.
